On behalf of Angle Tom:

The cast error occurs when using a build.gradle configured against a older version of Groovy (used by Gradle).

In this case, the issue with Gradle Idea plugin likely arises from the following example from the pre-2.0 Gradle docs which uses Groovy 1.8:

idea {
  module {
    scopes.PROVIDED.plus += configurations.provided
  }
}

From Gradle 2.0, Groovy was updated from 1.8 to 2.3.2 as mentioned in the release notes. The major bump to the Groovy version meant that the syntax for appending to lists changed. Thus the Gradle docs were updated to reflect this:

idea {
  module {
    scopes.PROVIDED.plus += [ configurations.provided ]
  }
}
