It does not seem to be in the specifications.. May be it can be done automatically through maven "parent" feature? That's a general question in regards to all libraries used.. Thanks! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/755480#755480] Start a new discussion in jBPM Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
