@spuder is this a work in progress? Building the plan did not install ant for me. It looks like the do_build and do_install callbacks don't do anything and I end up with an empty package.

I should have put WIP in the description. It needs more validation.

Ant shouldnt require compilation since it is a jar.

I put WIP on the title so folks know 😁

I've resolved the empty artifact.

This works, however it is still not getting JAVA_HOME set correctly. I don't understand habitat environment variables enough yet to know how to fix it.

hab studio -k foobar enter
build
hab pkg install /src/results/foo-bar-1.0.0.-xxxxx.hart
hab pkg exec core/ant ant
Error: JAVA_HOME is not defined correctly.
  We cannot execute java

Update

I wonder if this is actually be a problem with the java packages since java gives me the error 'no such file or directory'.

Closing in favor of #919. Thanks for the work on this one!
