ruby class to java class using jruby

i found the following ruby app in git: https://github.com/chrislo/sourceclassifier and it is exactly what i need for the final part of my school project. It would be great if i could use it in a my java project.

i used jRuby and managed to compile the class i need ( sourceclassifier.rb ) to a Java .class file, and added it to the build path of my eclipse app.

how can i now use it inside my app? using s开发者_如何学Goourceclassifier s = new sourceclassifier() throws me the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError: sourceclassifier/lib/sourceclassifier
    at StackOverFlowReader.main(StackOverFlowReader.java:208)
