Re: Maven coordinates going forward

[Paul King <pa...@asert.com.au>]

Thanks everyone for the feedback. I was mostly interested in feedback on
the maven coordinates rather than package names, but it was good to get
views on both. We have already started creating new classes using the
org.apache package prefix rather than org.codehaus and I presume that we
can continue doing that for now. But we haven't reached the point where we
have parallel Groovy2/3 versions (or whatever version numbers it ends up
being) of the same functionality. We might need to do an early spike to see
how things start to pan out. For the time being I'll leave the maven
coordinates using org.codehaus.groovy (so that's what snapshot versions
will have for now) and when it gets closer to a release of the version we
believe to have the envisaged significant breaking changes we can call for
a vote on a coordinate change. By that stage it will also hopefully be
clearer on what changes might need to be adopted wrt package names.

Cheers, Paul.
