Integrated code lifecycle: Make result processing more robust against invalid static code analysis file formats

[Strohgelaender]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I strictly followed the server coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).
• I documented the Java code using JavaDoc style.

Motivation and Context

@LordMuetze encountered an issue on production where students did not see any build results for their submissions.

Description

The issue was caused checkstyle throwing an error when processing a submission with a compilation error, leading to an invalid report file format. Since parsing the file did not work, the whole build did not produce any result at all.

We now catch such exceptions and continue processing the other files.

Steps for Testing

You need a java programming exercise with SCA enabled.

Submit code with a compilation error -> check that a result is visible indicating the compilation error.

Walkthrough

The updates in this set of changes focus on refining the handling of static code analysis and test result files within the build process. By enhancing error handling and exception management, the adjustments aim to promote a more resilient and efficient build operation that can navigate issues with report formats without halting the entire process.

Changes

File Path	Change Summary
.../localci/buildagent/BuildJobExecutionService.java	Adjusted processing of static code analysis report files with a try-catch block to handle exceptions more gracefully, specifically addressing invalid report formats.
.../localvcci/LocalCIIntegrationTest.java	Updated logic in testFaultyResultFiles() method to replace notification verification with a call to testLatestSubmission() from localVCLocalCITestService.

Possibly related issues

• Exam: Divide the Testing Process into Steps #6621: The changes in this PR could indirectly support the objectives outlined by ensuring that build processes, including test execution, are more resilient to errors. Specifically, by improving error handling in the build process, it could facilitate a smoother testing phase during exam programming exercises, aligning with the goal of reducing manual intervention and enhancing automation around test case management.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.

Tested on TS6.

• Enabled SCA and made a submission with a compile error
• Got a result with build failed ✅

Code lgtm. Also tested on ts6 and works as expected
