Re: [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-ut...) 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? --- regards Grzegorz Grzybek That sounds good. Please post to forge-dev(a)lists.jboss.org when you want help getting this rolling!
