What version of BlackBerry OS can I target with WebWorks SDK 2.0

It looks like I can't install WebWorks SDK 2.1 in Eclipse without having to build everything manually...screw that. I need to build my app for BB SDK 6, but I keep getting build errors on 6.0 API calls. I've set my default JRE to BB 6, but I seem to be getting facet errors.

The WebWorks Static Web Module doesn't want to play nice with everything else.

I'm I hosed on developing for BB6 or am I doing something wrong?!

Someone on the BB Dev forums mentioned the bbwp.properties file...apparently it has a property where you would specify the BB runtime or BB component pack. If th开发者_Go百科is is the correct approach could someone provide an example of the setting?
