Metro runtime in Eclipse

Can someone please explain how one can enable the Metro runtime in Eclipse. I have already tried the Glassfish budles. The runtime is available in the bundle and I know one option is to copy the metro "dropin" across. However, all the software has moved on and I wanted to pick up the most recent version of Metro.

I think some readers have created their own plugins. Some advise on this approach would be helpful but really Oracle should be doing more to support Eclipse.

Is this Oracle's not so gentle way of getting users to switch to netbeans?
