I've just created a plugin manually (grails create-plugin erik-first-plugin), and that works fine. I try to open it in IntelliJ (create new project, grails app), but IntelliJ wants to execute the create-app script. Makes sense, I guess, but the create-app creates a lot of extra artifacts, accourding to the console. I don't want that: I just want to use IntelliJ for editing my plugin. How can I do that??
