As far as I am aware, the Apache Groovy source explicitly imports and
uses the GnuParser – even now despite it being deprecated – as part of
the CliBuilder class. All other uses of org.apache.commons.cli in the
Apache Groovy source use DefaultParser. If I remember correctly,
DefaultParser, which is PosixParser I believe, enforces bursting of
single hyphen options, which is fine for the Groovy command line, but
not sufficiently flexible for the CliBuilder.

The "Java Way" is for a version of something, in this case Groovy 1.8.6
to retain its original dependency, in this case Commons CLI 1.2.x,
rather than have the dependencies altered without a new release – most
people get their dependencies from JCenter or Maven Central via Gradle
or Maven.

Apache Groovy 1.x series is no longer maintained. All effort is now on
the Apache Groovy 2.4.x and 2.5-SNAPSHOT versions. If Debian is to
remove Commons CLI 1.2 then I suggest removing the groovy package since
the groovy2 package is in place already, and is the right version for
Debian to go with.

Unless I am missing something.
