The patch has been updated a few times since I sent that email. New patch is

I will add a m2resource access to the unit test and more code comments and
update the patch.

I'd ask that you please reconsider this recommendation. I think the new
resolver is generically useful. Initial feedback on the ivy users list has
been encouraging. Including this in 2.0 would be a new feature addition that
people would appreciate and help show Ivy development and innovation is

Moreover, nobody is going to bother to download a separate plugin. Making
this a plugin is equivalent to killing the idea. We want to encourage people
to use Ivy, in whatever ways they want... not make it hard to do so.

The builder resolver is generic and not at all tied to the RoundUp project,
which is entirely separate. Contrast with the ivyrep resolver (which is
included in Ivy) which although now deprecated was originally tied to a
specific repository.

Also, I've included unit tests, complete
the code passes checkstyle, etc. I am already an Apache committer (from
early Harmony project days) and am willing to maintain this little piece of
the project.

In short, if you think this is a good idea overall, I don't see what
downside there is to going ahead and including it in Ivy now. The potential
upside, however seems very positive. We need a well-organized community

Thanks. Please consider adding to the RoundUp wiki site, especially the
your experience would be very valuable here.

I will work on setting up a mailing list too.
