Tuning Eclipse is pretty straight forward, passing the commonly documented command line arguments when running Eclipse on Mac OS X is not. At least not as easy as it would be in Windows. Like Windows shortcuts we have OS X ‘aliases’ but these do not allow us to specify additional arguments.

You can create a bash file to launch Eclipse with the extra parmeters but then we can’t place this on the Dock. Fortunately you can place these settings in the eclipse.ini – but where the hell is it?

Finder will then present a new folder window:

Voila! You can enter your VM args into eclipse.ini
