Java.lang.ClassNotFoundException: IntegrationSpec when running specs2 Tests in Intellij 14

What I've done:

• Install Intellij 14 (same problem appears with Intellij 13 as well)
• Install Scala 1.0 plugin for Intellij (supports Scala, SBT, SSP, HOCON and Play 2).
• Create a new Play 2.x project
• Run project from Intellij 14 (open via localhost: 9000 successfully)
• The default run tests (ApplicationSpec, IntegrationSpec) will not run due to the error message below.

Why won't test classes be generated when running tests by default?

Is there something wrong with my configs (see http://prntscr.com/53nk41 and http://prntscr.com/53nkj7 )?

Thanks for any advice!

Mistake:
