So what you're suggesting, even you stated differently is that you
want to pollute rubygems.org with maven artifacts wrapped as gems?

Simply because a maven dependency is not Ruby nor a RubyGem?

As long those tools use gem command line or Gem::Installer, those
hooks will be fired up automatically.

I have the feeling that no matter what solution we can come up with
will never be enough to you. I hint that you want rubygems.org
understand and host your maven dependencies.

What I suggested is a way that you can add a maven-logic layer to
RubyGems and be able to install those dependencies for the user, but
seems clearly discarded by you.

What you really want is be able to manage maven as gems from "gem"
command, something that I believe goes beyond the scope of RubyGems
(or Ruby) and that solves the needs of one single Ruby implementation:
jRuby.

Perhaps you need a way to plugin and extend Gem::Installer to fulfill
jRuby needs.
