# 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.
