Install any Java library as a JRuby gem

Posted by datazoo on March 15, 2010 — 2 comments
Charles Nutter: "... 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

“” My desire is that you'd be able to write an app entirely in ruby, including the use of gems, and then package that all up as an Android application, possibly precompiling it all to improve performance. It would probably be easiest if instead of using RubyGems proper you used Bundler, since then the RubyGems logic would not need to be shipped.
