Bug#839896: groovy.util.AntBuilder.class missing from /usr/share/groovy/embeddable/groovy-all-2.4.7.jar

[Emmanuel Bourg]

I haven't figured out the root cause of this issue but I've modified the
groovy package such that its build fails when AntBuilder is missing from
groovy-all.jar. That will allow me to upload a working package, but I
expect the build to be unstable with a 50% success rate.
