There seems to be no jBPM archetypes which we could use to start new projects based on jbpm. The only archetype which I found is "kie-drools-archetype". I was thinking that these would be nice to start with:

jBPM Process Project (kie-jbpm-process-archetype)
jBPM Process Blank Project (kie-jbpm-process-blank-archetype)
jBPM Case Project (kie-jbpm-case-archetype)
jBPM Case Blank Project (kie-jbpm-case-blank-archetype)
jBPM KJAR Project (kie-kjar-archetype)
jBPM KJAR Blank Project (kie-kjar-blank-archetype)
jBPM REST Process Project (kie-jbpm-process-rest-archetype)
jBPM REST Process Blank Project (kie-jbpm-process-rest-blank-archetype)
jBPM REST Case Project (kie-jbpm-case-rest-archetype)
jBPM REST Case Blank Project (kie-jbpm-case-rest-blank-archetype)
