问题
I've been trying on multiple machines, with multiple versions of Eclipse, JBoss Drools, and the Eclipse GEF (as stated in Drools docs as required).
I can't get them installed and working together, at all. See below for exact problem.
回答1:
In your question text you refer to Drools, but not jBPM. The install is choking on jBPM. Perhaps try installing Drools without the jBPM stuff? I'm running Drools 6.2.0.Final on Luna SR2 without issues, and I don't have jBPM installed.
If you still have problems there, you could try what @laune suggested: Drools 6.2.0.Final.
