Using Eclipse with JRuby Truffle

This is an experiment, mainly to have a much better feedback from the Truffle annotation processor.
(and ideally much faster compile time!)

Maven can be used to generate Eclipse project files:

mvn eclipse:eclipse

Create a new workspace in Eclipse, outside the jruby directory (otherwise Eclipse complains about overlapping dirs).

• From the main menu bar, select File > Import...
• Select General > Existing Projects into Workspace
• Enter the jruby directory in root directory
• Click Finish

Then you need to give the path to your Maven repository (usually ~/.m2/repository).
