Using Maven libraries from JRuby

Notice: This does not currently work with jgems and the feature itself may have been removed.

JRuby's version of rubygems has support for treating Maven dependencies as if they are gems. Just gem install mvn:[groupId]:[artifactId] and then require 'mvn:[groupId]:[artifactId]' in your ruby code.

An example:

gem install mvn:com.yammer.metrics:metrics-core

require 'java'
require 'rubygems'
require 'mvn:com.yammer.metrics:metrics-core'

counter = com.yammer.metrics.Metrics.new_counter(...)
