Install any Java library as a JRuby gem Charles Nutter said "… a prototype Maven server that looks and feels like a RubyGems source. By setting this server as a source (or passing it to the gem command), any Java library in the world is installable as a gem. Let me repeat that: ANY Java library in the world, installable as a gem. This means you can also use Maven artifacts as dependencies in regular Ruby gems, and it additionally means we won't have to re-release jar files into their own duplicate gems on the standard repositories. It's very exciting, and we hope to have it ready for JRuby 1.5." You can get it here: maven_gem at github
