Personally I'm not a big fan of eclipse, I much prefer IntelliJ IDEA for various reasons.
In the recent few days I've decided to make a gradle plugin that allows for fetching of WPILib resources, setting up of workspace/project and deploying code to the RoboRIO without the need for eclipse, only a command line and any IDE you like.
Here's the link to the project:
https://github.com/Open-RIO/GradleRIO
If you end up using it, let me know if you find any bugs
