There is a new experimental eclipse plugin available for Java programming. It has the features of the NetBeans plugin plus a "Robot Centric" view of your project. You can create devices and mechanisms by combining elements from the palette. You need to select the Robot Perspective in the Window menu to see all the new features. Please refer to the help that comes with eclipse for more information. And see the
FAQ (Wiki) for more information on installing and using the plugin.
Please post any issues in the Trackers area on the WPILib FIRSTForge project.
