Hello @holtskinner, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request introduces an initial sample for the Java Gen AI SDK, focusing on text generation. It includes a pom.xml file to manage dependencies, a TextgenWithTxt.java file containing the code sample for text generation, and a TextGenerationIT.java file for integration testing.

Highlights

• Dependency Management: The pom.xml file sets up the project with necessary dependencies, including the google-genai library and testing frameworks like JUnit and Truth.
• Text Generation Sample: The TextgenWithTxt.java file demonstrates how to use the Gen AI SDK to generate text from a prompt. It uses the gemini-2.0-flash-001 model to answer the question "How does AI work?".
• Integration Testing: The TextGenerationIT.java file includes an integration test to verify that the text generation sample runs successfully and produces a non-empty response.

Code Review

The pull request adds a basic text generation sample using the Java Gen AI SDK. The code is straightforward and easy to understand. However, there are a few issues that need to be addressed before merging.

Summary of Findings

• Copyright Year: The copyright year in the source files is set to 2025. Please confirm that this is the correct year, or if it should be updated to the current year.
• Missing API Key: The code does not include any mechanism for passing the API key to the GenAI client. This will cause the program to fail. Please add a way to pass the API key to the client.
• Exception Handling: The code throws IOException and HttpException, but doesn't handle them properly. It's important to catch these exceptions and handle them gracefully, or re-throw them with a more specific exception type.

Merge Readiness

The pull request is not ready to be merged. The copyright year needs to be confirmed, the API key needs to be passed to the client, and the exceptions need to be handled properly. I am unable to approve this pull request, and recommend that it not be merged until these issues are addressed, and that others review and approve this code before merging.

[telpirion]

From a style perspective, this looks fine to me. Looks like there are some CI/CD failures that need to be addressed.
