I guess the difference between jbpm-gpd-feature and jbpm-gpd site is that if you install site, it will take care of updating if there is any new version of gpd out there. What is the relation between gpd 3.0.11 and jbpm 3.1.2? As long as the par file is correct, jbpm 3.1.2 should work fine. I guess your question is gpd 3.0.11 on eclipse 3.1?
