# cache uses two files:
#
#   - gradle-wrapper-<os>-<arch>-<hash>:
#       contains the Gradle wrapper/distribution (~/.gradle/wrapper)
#       and is updated when the Gradle version changed
#   - gradle-caches-<os>-<arch>-<hash>:
#       contains the Gradle caches (~/.gradle/caches), buildSrc/build and buildSrc/.gradle
#       and is updated when Gradle related files were changed
#       buildSrc/.gradle is needed so that buildSrc tasks are UP-TO-DATE
