Here we disagree. I think it's perfectly reasonable to have a GPars
in a package separated from Groovy. Maybe somebody could want to use
GPars with a pure Java application, or in a Scala project, Clojure,
etc. You should not have to install GPars along with Groovy, but of
course Groovy is going to recommend GPars because enhances it.

That's right and that's why I decided to upload Groovy 2.1.x. I want
to update all Groovy libraries so we can have up-to-date libraries in
the next stable release.

As we already discussed in another email thread, GPars also migrated
to Gradle as build tool. So, to update GPars I see two options right
now:

* I wait until Gradle is based in Groovy 2.x.

* I build GPars with another tool (this was already done in the past
  with Ant but I don't know if I have the time to review that again).

Cheers,
