  # Build the jars twice. First with applying hiddenapi, creating a boot jar, then
  # a second time without to create a normal jar. We need to do this because we
  # want to load the jar once as an app module and once as a member of the boot
  # class path. The DexFileVerifier would fail on the former as it does not allow
  # hidden API access flags in dex files. DexFileVerifier is not invoked on boot
  # class path dex files, so the boot jar loads fine in the latter case.
