Class file for android.support.v4.widget.DrawerLayout not found - Intellij (UI 14.141.1192.2)

When compiling Gradle, it cannot find android.support.v4 even though it is correctly declared in build.gradle .

I am using the android-scala plugin which I think is not a problem because various other posts seem to have the same problem. Intellij displays libraries under the sidebar: "Project view", but at compile time the " android.support.v4 " library is not available, also not after cleaning. I have tried all the suggestions I could find on StackOverflow with no success.

Any help would be much appreciated

thank

Adam
