How to build redfire in Eclipse?

Hi all, I checked out redfire source and build a Eclipse project, but I do not know how to build the whole redfire. The build instructions for openfire and spark plugin seem invalid for it, the directory structure is not the same with common plugin directory structure.

Thanks!

I also want to know how to build redfire project,maybe we should use flashbuilder(since i saw many files end with “.as”).Looking forward someone who knows could help.Thanks Very Much!
