How to build the openfire project in Eclipse

I’ve got the openfire source code, but I don’t know how to build it, and debug it in Eclipse. Is there anybody could to help me? thank you…

Did the instructions under Openfire Dev / documents (http://www.igniterealtime.org/community/community/developers/openfire_dev?view=d ocuments), i.e. this file “Openfire SVN + Eclipse 3.3 + Subversive Installation Guide” (http://www.igniterealtime.org/community/docs/DOC-1020), not work?
