Compilation Error on Ubuntu 24.04: Could not resolve artifacts for configuration 'classpath' (builder-8.12.0.jar, core-proto-0.0.9-alpha03.jar, protos-31.12.0.jar)

[JocLRojas]

I am trying to compile the XtMapper project on Ubuntu 24.04 LTS using Gradle 8.14.3 and the Android plugin version 8.12.0, as per the project configuration. When running ./gradlew assembleDebug, I encounter dependency resolution errors for critical artifacts such as builder-8.12.0.jar, core-proto-0.0.9-alpha03.jar, and protos-31.12.0.jar. Gradle indicates that it cannot find these files in the configured repositories (specifically in https://dl.google.com/dl/android/maven2/).

Relevant Configuration:

• Gradle version: 8.14.3 (defined in gradle-wrapper.properties).
• Android plugins: Version 8.12.0 (in the project-level build.gradle).
• Kotlin: Version 2.2.0.
• Repositories: Using google() and mavenCentral() (configured in the build script).

Has anyone encountered this error with the Android plugin version 8.12.0? Are there additional repositories I need to add? Or should I downgrade the plugin to a more stable version? Any guidance would be appreciated.

It shouldn't be an issue with repositories. GitHub actions also runs on Ubuntu 24.04 and it can build the project without any issues: https://github.com/Xtr126/XtMapper/actions
I'd suggest trying to use a VPN in case your network blocks the repositories, wiping $HOME/.gradle, running ./gradlew clean.
