IntelliJ Grails app installed plugin not visible

Got a small question that ruins my day. I've got the Grails application that I want to import to IntelliJ. The problem is that IntelliJ can't find the springsecurity plugin, and doesn't see the开发者_开发百科 @Secured annotation. The plugin is present in the "Tools->Grails plugins" window.

I'm using Idea 9.0 and grails 1.3.5.

I would try IDEA X, a lot has happened in this field since 9.0. I'm using IDEA X build 98.311, and I'm able to see springsecurity plugin and the @Secured annotation
