Hacking on the Vagrant plugin

I highly recommend using RVM for this, my local .rvmrc for this project, which will never be checked in is as follows:

rvm use jruby@vagrant-plugin

This will make sure that I'm using the latest JRuby with a vagrant-plugin gemset.

Setting up your environment

You should really only need to run these two commands:

% gem install bundler
% bundle install

That should set up all the gems you need, which once installed you should be able to run:

% jpi server

Which will bring up Jenkins locally with the Vagrant plugin enabled.
