With a background in backend development and six months of Kotlin experience from an internship, I thought it would be cool to work on a multiplatform mobile SDK which increases accessibility to Firebase AI. + +My project focused on creating a Firebase KMP library that allows developers to use Firebase in their Android and iOS apps. The goal was to simplify how developers add AI-powered features to their apps. Alongside the library, I built sample code and documentation to help others use it easily. + +To craft a successful proposal, I shared my previous open-source work, laid out a detailed project plan, and even built a small prototype. Working with my mentors was a great experience – they offered valuable feedback and helped me refine my ideas. The most challenging part was getting familiar with KMP’s iOS side, but it turned out to be an amazing learning opportunity. + +Through this project, I gained hands-on experience in cross-platform development, SDK design, and open-source collaboration, as well as key skills in communication and documentation.

+
+ +Hailing from Cairo, Nouran Atef spent her summer making Gradle builds faster and more reliable. Her project tackled Configuration Cache compatibility across major community plugins, refactoring them to remove bottlenecks and enable smarter caching. She contributed fixes, documentation, and patterns now adopted across plugins, boosting performance for developers everywhere. + +**[Project page](https://community.gradle.org/events/gsoc/2025/configuration-cache-and-lock-contention/)** + +**Mentors**: Oleg Nenashev (ex-Gradle), Rafael Chaves (Gradle), Rodrigo Oliveira (Gradle) + + +## About the author + +Hi everyone\! I'm Nouran Atef, a senior computer engineering student from Cairo, Egypt. I'm passionate about developer tooling and open-source collaboration, and I love diving deep into build systems to make development faster and more efficient for everyone. + +## Why this project matters + +We've all been there: You make a tiny change, hit "build," and then wait... and wait. In large-scale projects, slow build times are a major drain on productivity. This is the exact problem my Google Summer of Code project with the Kotlin Foundation aimed to tackle. + +The goal was to improve support for Gradle’s **Configuration Cache**, a powerful feature that dramatically speeds up builds by caching the result of the configuration phase. When a plugin isn't compatible, the entire cache is invalidated, and the performance gains are lost. My project focused on identifying popular community plugins with these compatibility issues, fixing them, and contributing those fixes back to the open-source community. + +By making more plugins compatible, we make Gradle builds faster and more reliable, which is a huge win for developer productivity and CI stability across the Gradle plugins. + +## Technical highlights + +The primary technical challenge encountered was that plugins were accessing the live, non-serializable `Project` object during task execution, which is incompatible with the Configuration Cache. + +To solve this, I used a consistent strategy across several plugins: **decouple tasks from the live project model**. This meant reading all the necessary data during the configuration phase and passing it to the task in a safe, serializable way. + +My main tools for this were: + +1. **Serializable data transfer objects (DTOs):** I created simple data-holder classes to act as a "snapshot" of the required project information. +2. **Gradle’s lazy Provider API:** I used `Provider` to represent values that might not be known at configuration time, deferring their computation until they were actually needed. This allowed me to safely connect data from the plugin extension to the task inputs, ensuring proper task dependency tracking and configuration cache compatibility. + +## A few key contributions + +While I worked on several plugins, here are a few highlights: + +### 1\. Nebula Gradle Lint Plugin (gradle-lint-plugin) + +* **Problem:** The plugin's primary violation was its direct reference to the `Project` object and its use of `project.configurations` to resolve dependencies at configuration time. The direct `Project` reference has been successfully removed. +* **Fix:** The core approach was to decouple tasks and services from Gradle's live `Project` object. This was achieved through a consistent, two-pattern strategy: + 1. **Operate on data snapshots:** I created simple, serializable data containers (`ProjectInfo` and `ProjectTree`) to act as a "snapshot" of the necessary data, extracted using Gradle's lazy Provider API. + 2. **Defer access with a supplier:** For rare cases where a task absolutely required the live `Project` model at execution time, I used the serializable `Supplier`. This provides a "recipe" to get the `Project` object on demand, isolating the non-cache-friendly logic. +* **Technical write-up:** [Supporting Configuration Cache \- my learnings from the Nebula Lint Plugin](https://dev.to/gradle-community/unlocking-configuration-cache-with-gsoc-contributor-374l). +* **Pull request:** [\#433](https://github.com/nebula-plugins/gradle-lint-plugin/pull/433) + +### 2\. Liquibase Gradle Plugin (liquibase-gradle-plugin) + +* **Problem:** The main task accessed `project.properties`, `project.getProjectDir()`, and other `Project` APIs directly during execution. +* **Fix:** I introduced two DTOs, `LiquibaseInfo` and `ProjectInfo`, to capture all the necessary data at configuration time. The task was then refactored to operate on these DTOs, making its execution logic stateless and cache-friendly. +* **Pull request:** [\#176](https://github.com/liquibase/liquibase-gradle-plugin/pull/176) +* **Bonus:** This work was turned into a guide for the official Gradle Cookbook: [Case Study \- Enabling Gradle Configuration Cache Support in the Liquibase Plugin](https://cookbook.gradle.org/plugin-development/configuration-cache/example-config-cache-liquibase-plugin/?_gl=1*j978j1*_gcl_au*MTM2OTczMDc1MC4xNzYwNDU1NzUw*_ga*MzAxNTA3OS4xNzYwNDU1NzUy*_ga_7W7NC6YNPT*czE3NjA0NTU3NTEkbzEkZzAkdDE3NjA0NTU3NTkkajUyJGwwJGgw). + +### 3\. Compose Multiplatform Localization Plugin + +* **Problem:** The plugin's main task contained multiple Configuration Cache violations by accessing the `Project` object during the execution phase. Specifically, it used `project.projectDir` to resolve file paths and `project.logger` for logging messages. +* **Fix:** This was a more straightforward fix. I replaced the `project.projectDir` call with a lazy `@Internal` property and switched from `project.logger` to the task's own built-in `getLogger()` method. +* **Pull requests:** [\#12](https://github.com/hyperether/compose-multiplatform-localize/pull/12) and [\#13](https://github.com/hyperether/compose-multiplatform-localize/pull/13) + +## About My GSoC Experience + +I discovered GSoC while looking for ways to contribute to impactful open-source projects. The idea of working on developer tools that I use every day was incredibly exciting. I spent a lot of time studying Gradle's build lifecycle and the Configuration Cache documentation to write a proposal that outlined a clear, actionable plan for identifying and fixing issues in community plugins. + +Working with my mentors, **Rafael Chaves**, **Rodrigo Oliveira**, and **Oleg Nenashev**, was an amazing experience. They provided invaluable guidance, from high-level architectural advice to detailed feedback on pull requests. Their expertise helped me navigate the complexities of both Gradle and the various open-source projects I contributed to. + +The biggest challenge was the variety of plugin architectures. Each one required a unique approach, and some required deep architectural changes. It was a fantastic learning opportunity. + +Through GSoC, I've learned so much: + +* **Technical skills:** I gained deep knowledge of the Gradle API, build performance optimization, and advanced debugging techniques. +* **Tools:** I became much more proficient with Git and GitHub Actions. +* **Mindset:** I learned the art of open-source collaboration, how to communicate effectively with maintainers, respond to feedback, and patiently work to get contributions merged. + +This experience has solidified my passion for working on developer productivity tools.

This year, I had the incredible opportunity to work on a **Kotlin Foundation** project for **Google Summer of Code 2025**, contributing under the **Jenkins organisation** on the **Gradle Convention Plugin** project – an experience that blended my love for Kotlin, DevOps, and developer tooling. + +*The moment that acceptance email from Google landed in my inbox, I couldn’t stop smiling. I knew right then that my summer was about to be filled with code, learning, and a lot of open-source magic.* 😊 + +## Project overview + +While most of the Java and Kotlin ecosystem has embraced modern build tools like Gradle, with its fast builds and elegant Kotlin DSL, Jenkins plugin developers have largely remained tied to Apache Maven. It remains the primary and officially recommended build tool for Jenkins plugin development, powering the vast majority of plugins in the ecosystem. Its strong integration with the Jenkins plugin parent POM, extensive documentation, and mature lifecycle support make it the safest and default choice for most developers. + +Gradle support technically existed through the **Gradle JPI plugin**, but it came with major limitations: no native PCT support, fragile dependency management, and missing compliance for Jenkins hosting. In late 2022, the Jenkins community opened a [discussion](https://groups.google.com/g/jenkinsci-dev/c/lHQAiEepBiw?pli=1) highlighting significant gaps in Gradle support for plugin hosting and automation. During that time, new open-source Jenkins plugins using Gradle were temporarily blocked from hosting until those issues were resolved. + +![jenkins-gradle](gsoc3.png) + +The **Jenkins Gradle Convention Plugin**, developed as part of my Google Summer of Code (GSoC) 2025, offers a standardized solution for building Jenkins plugins with Gradle. This initiative arose from community discussions and efforts to address existing gaps. I built this plugin in collaboration with **Gradle**, **Netflix**, and the **Kotlin Foundation**, under the expert guidance of [Oleg Nenashev](https://github.com/oleg-nenashev), [Steve Hill](https://github.com/sghill), and [Rahul Somasunderam](https://github.com/rahulsom). + +It is a Kotlin-first Gradle convention plugin that acts as the Maven [parent POM](https://github.com/jenkinsci/plugin-pom) equivalent for Jenkins plugin development with Gradle. Built on top of the well-established Gradle JPI plugin, it provides a unified, opinionated foundation for building, testing, and publishing Jenkins plugins – standardizing best practices, automating quality checks, and eliminating boilerplate. It is an important step toward making Gradle a first-class citizen in Jenkins plugin development, closing long-standing gaps identified in prior community discussions. + +This plugin also showcases how Kotlin’s expressive DSL and strong type-safety simplify complex Gradle build logic, turning repetitive scripts into clean, reliable configurations. It also highlights Kotlin’s versatility – not just for building applications, but for building the infrastructure that powers them. + +## My GSoC journey with the Kotlin Foundation + +### The search that led me here + +Google Summer of Code (GSoC) has always been more than just a program – it’s where curiosity meets real-world contribution, and a dream opportunity for every tech enthusiast. Each GSoC season, I’d read about developers who started as users and went on to contribute to the tools they used on a daily basis. Every one of those stories left a spark in me – a quiet sense of inspiration and determination that someday, I would be part of that journey too. + +So, as I was scrolling through this year’s organizations and project ideas, a **Google Discover notification** popped up on my phone: *“*The Kotlin Foundation joins GSoC 2025\.*”* I paused for a moment – and honestly, my eyes lit up. Kotlin had been such a big part of my journey as a developer; the idea of contributing back to its ecosystem felt *right*. It wasn’t just excitement; it was an unmistakable feeling of **“this is where I’m meant to be.”** From that very moment, I knew I had found the organization I wanted to be part of. + +The next phase was project selection. I scanned through a broad range of projects across build systems, developer tooling, and multiplatform support. The “[Jenkins Plugins Toolchain / Gradle Convention Plugin](https://kotlinlang.org/docs/gsoc-2025.html#gradle-convention-plugin-for-developing-jenkins-plugins-easy-to-hard-90-hrs-to-350-hrs)” idea jumped out. It brought together everything I love – automation, Gradle, and the Kotlin ecosystem – with a clear goal of simplifying plugin development through consistency and convention. + +### Writing the proposal + +Crafting the proposal turned out to be an intense but deeply rewarding process. I spent a week diving deep into the pain points of Jenkins plugin development, studying how the existing **Gradle JPI plugin** worked and where it fell short, and going through the community discussions to understand what developers struggled with the most. My goal wasn’t just to offer quick patches/fixes, but to design and implement a solution that genuinely enhanced the developer experience. + +Once I felt confident about the direction, I began writing the proposal – gathering resources, watching talks on Gradle plugin development, exploring Jenkins repositories, and falling down more than one rabbit hole along the way. I built a small **prototype** to enhance my understanding and showcase the idea in action. After drafting my initial proposal, I shared it with **Oleg**, the **organization admin**, who gave me insightful feedback. Shortly after, Oleg scheduled a quick **virtual coffee chat**, where we discussed the project, my motivations, and how the idea could evolve during GSoC. That conversation gave me a clearer vision of what lay ahead and transformed my excitement into genuine momentum. + +### The selection moment + +When the results were announced, I remember refreshing my inbox late at night – heart racing – and there it was: *“*Congratulations\!*”* I had been selected. That single word felt like the reward for weeks of effort, late nights, and hard work. I couldn’t help but smile, and the first thing I did was tell my family – they were just as excited as I was. + +### Community bonding + +The **Community Bonding Phase** that followed next kicked things off with introductions, aligned goals and expectations, and set up communication channels to keep the project on track. I spent time configuring my development environment and exploring the Jenkins plugin ecosystem more deeply. + +### First Coding Phase: Laying the foundation + +Once the community bonding period ended, it was time to roll up my sleeves and dive into the code. The first few weeks were all about understanding how the Jenkins plugin ecosystem worked in practice, experimenting, breaking things, and learning fast. My primary focus was simplifying dependency management with the [Jenkins Bill of Materials (BOM)](https://github.com/jenkinsci/bom) and wiring up the basic Gradle conventions. I added support for code-quality tools like **Checkstyle**, **SpotBugs**, **Detekt**, etc., making plugin builds cleaner and more reliable by default. I began testing the convention plugin on several Jenkins plugins already built with Gradle to see how it performed in real-world scenarios. That phase gave me confidence that this project wasn’t just an experiment anymore; it was becoming something developers could truly depend on. + +### Mid-term evaluation: Building momentum + +By mid-term evaluation, I had to demonstrate working BOM integration, quality tool setup, and working examples. The pressure was real, but passing that evaluation with positive feedback from my mentors was one of the proudest and most fun moments of my summer. + +Here is my demo from the mid-term evaluation: [Google Drive Link](https://drive.google.com/file/d/1VaGFiRP466RS1FyaT6rT7xskZKXJ50x_/view?usp=drive_link). + +### Final Coding Phase: Bringing it all together + +Everything came together in the last stretch. I concentrated on enhancing support for [Plugin Compatibility Tester (PCT)](https://github.com/jenkinsci/plugin-compat-tester), streamlining metadata production, and getting the plugin ready for public release. It seemed like a full-circle moment to submit the plugin hosting request and have it approved by the official [Jenkins](https://github.com/jenkinsci/) organisation. Writing a [community blog post](https://www.jenkins.io/blog/2025/08/31/aarav-mahajan-gsoc-gradle-convention-plugin-for-jenkins-plugin-development/), documenting the plugin, and getting early feedback from developers who were testing it out were how I ended the summer. + +### Working with my mentors + +I would say this was one of the most rewarding parts of this journey. Oleg, Steve, and Rahul weren’t just reviewers; they were guides who challenged my assumptions, encouraged experimentation, and shared insights from real-world experience. Our discussions often went beyond the project itself, touching on design philosophy, long-term maintainability, and open-source collaboration. The feedback that they provided shaped not just my code, but my approach to problem-solving. This taught me more about modern software engineering than any textbook could. + +### Challenges along the way + +The steep learning curve of understanding Jenkins’ plugin architecture, coupled with Gradle’s evolving APIs, tested my patience and adaptability. Some days, I spent long hours debugging tricky build issues, ensuring cross-version compatibility, meeting Jenkins hosting requirements, wiring up code-quality tools, and refining every small piece until the build felt truly production-ready. Integrating the **Jenkins BOM** and **Plugin Compatibility Tester (PCT)** added another layer of complexity, as I had to ensure the plugin worked seamlessly across multiple Jenkins core and dependency versions. Every roadblock taught me something. I learnt how to break down complex problems, research effectively, and approach debugging with structure without losing my cool. + +### What this journey taught me + +This project was a crash course in real-world engineering. I deepened my understanding of **Gradle plugin development**, **Jenkins’ build ecosystem**, and modern **toolchain management**. On the non-technical side, I learned how to plan deliverables, communicate progress clearly, and write maintainable, community-friendly code.

+
+ +For Victoria Alajemba, a Software Engineer from Nigeria studying in Paris, GSoC was a bridge between learning and impact. Working on the IntelliJ Platform Gradle Plugin, she integrated Gradle’s Problems API and Reporting API, creating richer, standardized reports and exploring parallel verification for faster builds. Guided by Jakub Chrzanowski from JetBrains, she strengthened key workflows used by thousands of plugin developers. + +**[Project page](https://dev.to/victoria_chuks_7e772e1688/gsoc-2025-kotlin-foundation-final-report-3p4c)** + +**Mentor:** Jakub Chrzanowski (JetBrains) + +## About the author + +I am Victoria Chuks Alajemba, a software engineer passionate about developer tooling from Nigeria. I’ve been building mobile applications professionally since 2021, after learning programming via YouTube in 2020, and I am currently exploring the world of plugins and extensions across several platforms like the IntelliJ Platform, VS Code, Chrome, and more. I love developer tools and programming in general, but more than that, I love the idea of being able to create something that solves a problem. I currently study artificial intelligence and data science for businesses at aivancity School of AI & Data for Business & Technology in Paris. + +## Intro and motivation + +### Why this project matters + +The IntelliJ Platform Gradle Plugin is a critical tool for developers building plugins that target the IntelliJ Platform. It is used by JetBrains and third-party developers to build, test, verify, and publish their plugins. Improvements to this tool will ensure that the thousands of developers who rely on it have a great experience. + +### The problem it solves + +The verifyPlugin task, a Gradle task that is part of the IntelliJ Platform Gradle Plugin, enables developers to check that their plugin works against various IntelliJ-based IDEs (PyCharm, Android Studio, IntelliJ IDEA Community Edition, and more). However, the IntelliJ Platform Gradle Plugin team had identified certain areas for enhancement: + +1. **Non-standard reporting:** The verifyPlugin task used its own custom reporting system rather than Gradle's Reporting API, making reports less configurable and harder to integrate with standard Gradle workflows. +2. **Limited error context:** Build issues that were reported could benefit from a more detailed and structured process with the Problems API. +3. **Unclear performance characteristics:** We needed to investigate whether parallel execution could speed up verification against multiple IDE versions. + + +## Technical highlights + +### Core technical achievements + +#### Gradle Problems API integration ✅ Merged [PR \#1987](https://github.com/JetBrains/intellij-platform-gradle-plugin/pull/1987) + +* Replaced ad-hoc error reporting in VerifyPluginTask with Gradle's structured Problems API. +* Enhanced error reporting with contextual details, file locations, suggested solutions, and documentation links. + +#### Gradle Reporting API integration ✅ Merged [PR \#2016](https://github.com/JetBrains/intellij-platform-gradle-plugin/pull/2016) + +* Implemented VerifyPluginConfigurationReportsImpl with ReportContainer\ for standardized reporting. +* Added TXT report support with configurable output locations via the Gradle DSL. +* Integrated the Reporting\ interface for task-level report configuration. +* Demonstrated successful Reporting API usage in simpler validation contexts. + +#### Gradle Reporting API for VerifyPluginTask 🔄 [Draft PR \#1996](https://github.com/JetBrains/intellij-platform-gradle-plugin/pull/1996) + +* Implemented ReportingContainer supporting HTML, Markdown, and plain text reports. +* Exposed configuration through IntelliJPlatformExtension for user customization. +* Blocked by IntelliJ Plugin Verifier's single output directory limitation. + +#### Parallel verification research 🔍 [Closed PR \#1948](https://github.com/JetBrains/intellij-platform-gradle-plugin/pull/1948) + +* Prototyped a Gradle Worker API for concurrent verifyPlugin execution against multiple IDE versions. +* Discovered IntelliJ Plugin Verifier already uses internal ExecutorService concurrency. +* Identified the true bottleneck: sequential IDE dependency downloads (not verification). +* Researched dependency substitution, a ResolutionResult API, and parallel resolution strategies. + +#### Gradle Cookbook documentation ✅ [Merged PR \#58](https://github.com/gradle/cookbook/pull/58) + +* Authored a practical guide on wiring the Reporting API into plugin tasks. +* Provided configuration examples and best practices for plugin developers. + + +### Features, architecture, and key gains + +#### Key features + +* **Structured problem reporting**: Consistent issue visualization across IDEs, consoles, and BuildScans. +* **Configurable reports**: DSL-based report format and location customization. +* **Rich error context**: File locations, documentation links, and suggested solutions. +* **Gradle ecosystem alignment**: Leverages Problems API (Gradle 8.6+) and Reporting API standards. + +#### Architecture + +##### Problems API architecture + +* **Problems.kt**: Centralized registry of `ProblemIds` organized by: + * `ProblemGroups + Groups.VerifyPlugin` for verification-specific issues. + * Dynamic `VerificationFailure` factory generating `ProblemIds` from `FailureLevel` enum. + +```kotlin +/** + * Contains problem IDs to be used when reporting a problem with the Problems API + * for the IntelliJ Platform Gradle Plugin. + * + * @see org.gradle.api.problems.ProblemId + * @see org.gradle.api.problems.Problems + */ +@Suppress("UnstableApiUsage") +internal object Problems { + + /** + * Contains [ProblemGroup]s to be used with the Problems API for the IntelliJ Platform Gradle Plugin. + */ + private object Groups { + val IntelliJPlatformPlugin = ProblemGroup.create( + "intellij-platform-plugin-group", + "IntelliJ Platform Plugin Problems" + ) + + val VerifyPlugin = ProblemGroup.create("$ID.verify-plugin", "Verify Plugin") + } + + object VerifyPlugin { + val InvalidPlugin = ProblemId.create( + "invalid-plugin", + "Invalid Plugin", + Groups.VerifyPlugin, + ) + // .... + } +} +``` + +* **`reportError()` helper**: Wraps exceptions with Problems API metadata, including clickable report URLs. + +```kotlin +/** + * Helper function to report an error using the Problems API. + * + * @param exception The exception to report.

At my core, I see myself as more of a user than just a developer, so I'm passionate about improving the tools I actually use daily. + +### How I created the successful proposal + +Creating my proposal was an intensive research process that took several weeks, and here's how I approached it: + +#### Communicating with the organization + +While putting together my proposal, I made sure to ask questions about it on the org’s Slack channel. Doing this demonstrated my dedication and the kind of insight I already had for the project. + +#### Understanding the codebase (3–4 weeks before the proposal deadline) + +I dived into the IntelliJ Platform Gradle Plugin source code, focusing on the key parts outlined in the project description: + +* I focused on VerifyPluginTask and discovered it extends JavaExec and delegates to the Verifier CLI. +* I found the TODOs in the codebase that specifically mentioned Worker API and Reporting API integration – these became my project's foundation. +* I examined how VerifyPluginTask calls the external tool in its exec() method: + +```kotlin +@TaskAction +override fun exec() { + with(ides) { + ... + args(listOf("check-plugin")...) + ... + ByteArrayOutputStream().use { os -> + super.exec() + } + ... + } +} +``` + +* I analyzed the IntelliJ Plugin Verifier tool itself, discovering that it already implements parallelization using `ExecutorService` in `com.jetbrains.pluginverifier.runSeveralVerifiers`. + +#### Learning from other plugins (2–3 weeks before the deadline) + +I researched similar implementations in the Gradle ecosystem: + +* **For the Worker API:** I studied paperweight, Kotlin Benchmark, compose-multiplatform-core, and spotbugs-gradle-plugin to understand Worker API patterns and best practices. +* **For the Reporting API:** I examined Teamscale Gradle Plugin, inspection-plugin, and spotbugs-gradle-plugin to see how they implemented custom reports. + +#### Building a proof-of-concept (2 weeks before the deadline) + +I also built prototypes: + +1. **Reporting API prototype:** I created a working implementation on VerifyPluginProjectConfigurationTask (a simpler task that handles its own reporting). This proved that Gradle Reporting API integration was feasible and showed I understood the technical challenges. + +2. **Worker API prototype:** I implemented a basic Worker API integration for VerifyPluginTask using process isolation mode: + +```kotlin +abstract class VerifyPluginTask : DefaultTask() { + @get:Inject + abstract val workerExecutor: WorkerExecutor + + @TaskAction + fun verifyAction() { + val workQueue = workerExecutor.processIsolation() + workQueue.submit(VerificationTaskWork::class.java) { + // Set parameters for isolated execution + } + } +} +``` + +[Full implementation available here](https://github.com/alajemba-vik/intellij-platform-gradle-plugin/commit/6fbc444caf66481c8058c6e947874842ffd7f3e0). + +#### Identifying risks honestly + +I identified potential blockers: + +1. **Worker API risk:** Process isolation might introduce performance overhead that needs extensive testing. +2. **Reporting API challenge:** Since `VerifyPluginTask` delegates reporting to the Verifier CLI, we might need to update the CLI to output `List\` differently. +3. **External dependency concern:** IntelliJ Plugin Verifier is used by JetBrains Marketplace and external tools like GitHub Actions, so changes need careful consideration. + +Being upfront about these risks showed I understood the complexity, not just the ideal outcomes. + +#### Creating a realistic timeline + +I broke down my timeline into specific, measurable tasks: + +* **Before May 8:** Research and documentation study. +* **Before June 2:** Codebase analysis and prototype refinement. +* **June 1 – July 13:** Implementation with unit and integration tests. +* **July 14 – August 25:** Performance benchmarks, documentation, and finalization. +* **Plus:** A 3-week buffer for unpredictable delays. + +#### Being authentic about my experience level + +I was honest about my situation and experience: + +* I found large codebases like the main Kotlin repository daunting. +* I saw GSoC as an opportunity to learn how to become a better open-source contributor. +* I also acknowledged a personal constraint: I'd be starting my first year at aivancity School of AI & Data for Business & Society in September, so I planned to complete the coding portion before then. + +I also highlighted relevant experience: + +* Building IntelliJ Platform plugins (Flutter Image Icons, PokéPop). +* Contributing to Jetpack Compose Samples and kotlin-web-site. +* Documenting my migration to IPGP, showing I understand user experience. + + +### What I think made my proposal stand out: + +1. **Working prototypes:** I showed that I could execute the core ideas proposed. +2. **Deep technical understanding:** I demonstrated knowledge of the codebase architecture. +3. **Honest risk assessment:** I identified blockers and dependencies upfront. +4. **Realistic timeline:** My schedule was detailed and included buffers. +5. **User-focused motivation:** I emphasized improving tools I actually use, showing genuine investment. + + +### Lessons from the proposal process: + +* **Spend enough time on your proposal:** I dedicated a total of over 96 hours to putting together my proposal, allowing me to deep dive into different areas. +* **Build something:** Even a small prototype demonstrates capability better than any written description. +* **Ask questions:** I reached out on Slack to understand the project scope before finalizing my proposal. +* **Be honest:** Acknowledging what you don't know yet is more valuable than pretending to know everything. +* **Show, don't tell:** Code snippets and concrete examples made my proposal tangible. + +Looking back, the time I invested in understanding the architecture and building prototypes was crucial.

I’ve been at my company for a little over a year now and was excited about the opportunity to take part in Google Summer of Code (GSoC) 2025\. My proposal was *Enhanced Kotlin Code Quality Reporting with Gradle Problem API: Integration with Detekt and Ktlint*. + +## Motivation + +As developers, we always favor tools that enhance and streamline the programming process, including plugins that provide error reporting and insights to improve code quality. Kotlin developers using Gradle rely on tools like Detekt and Ktlint to enforce code quality. This project aimed to implement a unified and actionable code quality reporting system through the integration of the recently introduced Gradle Problems API. As an engineer who uses tools like Detekt and Ktlint daily, I wanted the opportunity to contribute to these popular tools to enhance their usefulness. This past summer I was also exploring how to make a linter or a plugin, so this project also gave me more insight into that. + +## GSoC experience + +I discovered GSoC a couple years ago when my previous mentor mentioned it when I was looking for summer internships and did not have any luck elsewhere. Unfortunately the deadline to apply to be a contributor had passed at that time, but I kept it in my back pocket to apply for in the future. + +Since I am a full-time Android Engineer, I wanted to contribute to the Kotlin Foundation, as that is the language we use to develop our Android app. I wrote the proposal and met with the potential mentors to talk more about implementation and my goals for the project. To my surprise, my proposal was accepted! + +Now, of course, I encountered challenges along the way. Learning about plugins took extra time, having a full-time job when we were coming out with big and new feature releases that I was leading did not help, and a small but noticeable one was the time difference between me and my mentors. The last one wasn’t too bad, but when things started to pile up at work or when I had to prepare for my conference talks, it did take my focus away from this project. + +Some takeaways are that I learned more about how plugins work, learned about open source, and connected with people that I would normally not have the chance to. I am still interested in open-source projects, but not necessarily plugin development. Nonetheless I enjoyed participating in the project and have a couple PRs that I need to fix up before they can be merged. You can find the project page [here](https://community.gradle.org/events/gsoc/2025/kotlin-code-quality-with-problems-api/), which also has the linked PRs. Collaboration, communication, and more Kotlin, of course, were skills I practiced during this project, which I am grateful for since they all contribute to becoming a better and more well-rounded engineer. + +Participating was a rewarding experience, and it opened up my eyes to the open-source community. To anyone considering GSoC, especially beginners, I would say to apply\! It is very beginner-friendly, and you can acquire valuable skills that you would not easily gain elsewhere. Below are some links where you can find me and my work\! Thanks for reading about my GSoC journey. + +## Resources and contacts + +You can see what other things I am working on or have done thus far on my [website](https://vanessajohnson.vercel.app), where you can also find links to my most recent talks if you are interested\! I also have a [newsletter](https://vanessaonmobile.substack.com) that I try to stay consistent with, which is about mobile application development and any projects or conferences I have in flight.
