we could bridge the Karaf commands so they are usable inside Forge; not sure it makes sense - but its certainly possble ;)

We have a static list of archetypes in fabric8 (they are all generated programatically too which helps ;), the code to generate them (ArchetypeHelper); so we just need 2 Java classes writing for the Karaf/Gogo shell and we’re done ;)

Something a bit more extensible, eventually, might be nice for Forge; though for fabric8 just having a curated list of archetypes from the fabric8 project itself will be fine for us for a while ;)

We went the maven archetype direction in Fuse IDE (now the Fuse / Camel tooling in JBDS) and now have lots of archetypes (both on upstream projects like camel & cxf and in JBoss Fuse); so I’m personally more keen to support archetypes ASAP; but the more tooling and options the better! :)
