[forge-dev] Forge and Camel Archetypes

Hello
Finally I have time to start the discussion about the use of Maven
Archetypes in both JBoss Fuse and JBoss Fabric.
Here are the links to relevant issues:
- https://issues.jboss.org/browse/FORGE-273
- https://github.com/fabric8io/fabric8/issues/1091
Currently we have (here:
https://github.com/fabric8io/fabric8/blob/master/tooling/camel-tooling-util/src/main/java/io/fabric8/camel/tooling/util/ArchetypeHelper.java)
a helper which can unpack maven archetype and correctly replace ${VAR}
variables in archetype resources.
Let's first say what we want to achieve. I'd say (please provide
comments if I misunderstood something):
Basic:
- to be able to unpack any Maven Archetype JAR and create working
("mvn clean install"able) project in FileSystem *without* using Maven
archetype-related libraries
- to be able to replace variables in archetype resources
- to be able to evaluate Velocity expressions (they may be present in
the archetypes)
Discovery:
- to be able to read list of available archetypes
- to be able to discover available archetypes and create the above
list (explicit distinction to free ourselves from finding the archetypes
in M2_REPO each time)
Help:
- to be able to discover archetype parameters (this is the main goal -
to make something more user/tab-completion friendly than "mvn
archetype:create" with millions of options)
- to provide commands (Karaf/Gogo or JBoss Forge) for project creation
- to ask users (GUI? Console? Hawt.io?) for required archetype:create
params
OK. I'd like to start a project (https://github.com/forge/ or
https://github.com/fusesource/ or https://github.com/jboss/ or
https://github.com/jboss-fuse/ - any suggestions?) which will do most of
the above and will be a foundation of:
- karaf/fabric command
- Forge addon(?)
Any suggestions?
