# Groovy's build system is Ant based, but they use Maven for fetching the dependencies.
# We just have to remove the fetch dependencies target, and then we can use Ant for this ebuild.

# We currently do not build the embeddable jar (which is created using JarJar).
# We could provide that via a USE flag.
# We also don't use automatic build rewriting as there seems to be already some level of support
# in the upstream build system

# TODO: Install all 3 documentation packages. Currently only the Groovy GDK documentation is installed
# as our java-pkg_dojavadoc function does not support multiple Javadoc installations.
