Here's the deal, I use Wro4j to handle the transpilation/'building' of .coffee files to .js ones.
Now I want to have a good editor plugin which supports CoffeeScript, and I don't want to install Aptana (I only need CoffeeScript, not Python, Ruby and all the other stuff it includes and doesn't let me choose not to install...).
Many thanks!
Have you tried coffeescript-eclipse plugin?

Besides CoffeScript-Eclipse: https://github.com/adamschmideg/coffeescript-eclipse (mentioned by BluesRockAddict), the other choices I know of are:
LiClipse: http://brainwy.github.io/liclipse/
Aptana Studio 3: http://www.aptana.com/products/studio3
