Automating Inclusion of Required Ruby Modules in JRuby Jar

[Dan King]

Is it possible to automate the inclusion of required Ruby modules in (JRuby) jars? Currently, I'm manually copying module files into a 'lib' directory within the main project directory from which I create a jar. I posed this question on the jruby mailing list and I was advised that 'warbler' can automate the process. However, it appears 'warbler' automates the jar creation process, but not the inclusion of required module files.

Assuming that by modules you mean gems, then Bundler is your best bet:

Rails 3 ships with Bundler. If you're not using Rails 3, you can still install Bundler as a gem.

A normal bundle install will only save gems to your local system. However a bundle package will include the gems in the project itself:

You will likely still use warbler but do so after running bundler.
