Scala global

I have a maven multi-module scala project (not SBT).

I have just upgraded to the new version 14.0.2 from 13.1 and I have created a scala global library.

I can make my project (ctrl-F9).

But the "display" compiler is complaining that scala library classes aren't resolved, e.g. "Cannot resolve symbol Seq"

scala plugin 1.2.1

scala version 10.2.4
