IDEA(Ultimate v.14.0) with scala plugin(v.1.1.1) do not compile test classes

Question

Today I have updated the scala-plugin to v.1.1.1 in IDEA Ultimate v.14.0 and now I can't execute tests via IDEA.
I get an exception: java.lang.ClassNotFoundException: models.HelloWorldSpec

I noticed that test classes do not appears in 'target/scala-2.10/test-classes' after compilation via IDEA. But all good when I execute 'sbt clean compile test' in the console.
