>          Components: build
>            Reporter: Greg Harris

> Reproduction steps:

> 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.
