-----------------------------------
Summary: Gradle build fails with missing commitId after git gc
Key: KAFKA-14767
URL: https://issues.apache.org/jira/browse/KAFKA-14767
Project: Kafka
Issue Type: Bug
Components: build
Reporter: Greg Harris
Reproduction steps:
1. `git gc`
2. `./gradlew jar`
Expected behavior: build completes successfully (or shows other build errors)
Actual behavior:
{noformat}
Task failed with an exception.
-----------
* What went wrong:
A problem was found with the configuration of task ':storage:createVersionFile'
(type 'DefaultTask').
- Property 'commitId' doesn't have a configured value.
Reason: This property isn't marked as optional and no value has been
configured.
Possible solutions:
1. Assign a value to 'commitId'.
2. Mark property 'commitId' as optional.
Please refer to
https://docs.gradle.org/7.6/userguide/validation_problems.html#value_not_set
for more details about this problem.{noformat}
This appears to be due to the fact that the build.gradle determineCommitId()
function is unable to read the git commit hash for the current HEAD. This
appears to happen after a `git gc` takes place, which causes the
`.git/refs/heads/*` files to be moved to `.git/packed-refs`.
The determineCommitId() should be patched to also try reading from the
packed-refs to determine the commit hash.
