I just read the InfoQ interview about version 7. Mike makes it sound like the Ruby/ROR plugin is taking precedence over the Groovy/Grails plugin. This is disappointing to me. Last time I checked, IDEA is a Java IDE and since there is a "pure" Java scripting language available (Groovy), this is a better fit than a non-Java language (Ruby) that doesn't play a role anywhere in the J2EE stack. Aside from the ROR hype, why should Ruby be supported in a Java tool at all?
Don't get me wrong, I think IDEA is a great tool but the GroovyJ plugin falls short when it compares to the developer productivity (completion, refactoring, debugging, etc) of the built-in Java support. Our team is a Java shop and uses Groovy on production reports and we need 1st class Groovy support. When our company becomes a Ruby shop (never), then I'll look to buy a Ruby IDE. Thanks for keeping the focus.
