This PR is to publish all the failng tests for each gradle-check job runs.
The results will be indexed into our metrics cluster (publicly available).
A sample record would look like.

{
  "build_number": 116,
  "pull_request": "PR #12503",
  "pr_description": "removing unused fetch sub phase processor initialization during fetch",
  "test_class": "LibraryTest",
  "test_name": "test.java.LibraryTest.testNewLibraryMethod",
  "test_status": "FAILED",
  "build_result": "FAILURE",
  "test_fail_count": 2,
  "test_skipped_count": 0,
  "test_passed_count": 0,
  "build_duration": 10071,
  "build_start_time": 1710541261641
}

This script will be added to the post action block of gradle-check.

The PR has no tests due to lack to support for jenkins internal methods, specifically currentBuild object.

Hi @rishabh6788 ,

Add some comments.

Thanks.

Maybe rename it getGradleTestResults? since these are specific to the gradle test?

[rishabh6788]

Renamed.
