I > don't like either of those options. This currently fails because rubygems.org makes sure that there is an existing gem on rubygems.org for each requested dependency. It only checks the presence, not the versions required by the dependency. Given that it's just checking the name and thusly not checking if the gem is actually usable with the requested dependencies, I think we should go ahead and remove the requirement all together. If we want to be nice to the user and indicate to them that their may be a problem with their gem, it's best to do that at 'gem push' time rather than enforcing the policy on rubygems.org. > > * A way for Bundler to recognize Maven dependencies as though they are gems. > > I'm looking for thoughts and suggestions on how we can make this > easier.
