The four ecore files correspond to the models defined in the BPMN 2.0 specification - there is no unified BPMN2 model, nor should there be because each of these defines its own namespace URI, and each is intended to stand alone. Your genmodel should only target the BPMN2.ecore, and use the other three as references. What kinds of problems are you having? You may want to research the EMF Model Generator and post your questions to the EMF forum.
