Re: [weld-dev] Weld archetypes in the spotlight

One significant difference is that an archetype gives you a starter application, but really knows nothing about your application. A mojo can be run at different points of the maven lifecycle, but doesn't know much about the app it's being run on. It's up to the mojo writer to turn the collection of classes and resources into meaningful pieces of an application. I can't speak for rails, but I know Grails actually is aware of your data and has a much richer model. Grails can apply a template per each entity or database table in your application. Maven, as of 2.2 (haven't looked at 3.0 yet), has no idea what your domain is. For example, if you wanted to create a plugin that generated a CRUD app per each entity in your application, your Maven2 mojo would have to start from scratch and determine what your entities are. It is my understanding that Grails plugins have convenient hooks to that data, controllers, service, etc (although someone who has actually written a Grails plugin before would be a better source of details on the subject).

Plugins provide: - a way for developers to share bleeding-edge ideas without hurting the stable code base - a segmented architecture so that units of code can be fixed or updated on their own release schedule - an outlet for the core developers so that they don’t have to include every cool new feature under the sun http://guides.rubyonrails.org/plugins.html Sounds like CDI PEs (portable extensions) was a ripoff of this idea... And wasn't seam-gen alarmingly similar to Grails in terms of quick project setup/startup? PE is strikingly similar to Rails plugins based on the above description when you think of Seam 3 having Weld as its new core and the "extras" like jBPM integration, remoting, iText, PDF, Excel, etc. Maven 2 already has the concept of MOJO (Maven POJO) and plugins: http://maven.apache.org/guides/plugin/guide-java-plugin-development.html Not sure what added-value you're suggesting??
