On the bottom of your Project Explorer, you will see "Build Specifications". Expand that, and you will see "FRC Robot Boot-Up Deployment". Right click on this and select "Build". This will build your project (it does not need an active connection to the robot to do this). Once this has completed, right click again and select "Run as Startup". When it has completed, it will ask you if you want to reboot the controller (select yes, it will reboot automatically). Your code should then be persistent on the controller.
