I'm trying to add more commands in Forge... but I have to say, I'm a bit lost. So, I've made a quick UML class diagram.
As you can see in the attached diagram (UIForgeNow.png), most of the Java EE commands extend AbstractJavaEECommand, which makes sense. But not all of them (NewBeanCommand (CDI), ValidationNewAnnotationCommandImpl, NewQualifierCommand....). And some times you have an extra level of abstraction (AbstractFacesCommand). Same for the Java commands. JavaClassCommandImpl extend AbstractJavaSourceCommand but JavaAddAnnotationCommand and JavaFieldCommand inherit from AbstractProjectCommand. Some other commands, just use the @Command annotation.
Then, when you dive into a command (UIForgeStructure.png), some commands use interface and implementation (see in the second diagram JavaAddAnnotationCommandImpl implementing JavaAddAnnotationCommand), some don't (e.g. NewQualifierCommand).
Correct me if I'm wrong, but the way I see it would be (UIForgeRefactor.png) : under AbstractJavaEECommand you have a set of AbstractValidationCommand, AbstractCDICommand, AbstractJPACommand.... each implementing PrerequisiteCommandsProvider (this way, each command sets up its own pre-requisite). And then, under AbstractCDICommand you have all the NewQualifierCommand, NewBeanCommand....
The idea of this JIRA is to brainstorm about refactoring the commands, and see if we do it and how
