    required: false
    default: ${{ github.event.repository != null && github.ref_name != github.event.repository.default_branch }}

  cache-write-only:
    description: |
      When 'true', entries will not be restored from the cache but will be saved at the end of the Job.

      Configuration-cache data will not be saved/restored without an encryption key being provided.      
    required: false
