      Issue Summary

      At some conditions Bamboo is unable to clear inconsistent git cache and perform change detection

      Steps to Reproduce

      1. none
        It seems that this happens if the change detection and the branch detection run at the same time.

        Expected Results

      When the git cache is inconsistent should be deleted and recreated.

      Actual Results

      The detention of the cache fails:
