[Play2] Cannot run Play2 project using "Play2 App" Configuration

Hi,

I created a "Play 2 App" Configuration to execute my Play2 Scala application from IntelliJ 13.0.1 Build #133.286 (Ubuntu 12.04.3 LTS). It failed because it cannot find the class  com.pty4j.PtyProcess as shown in the exception I have attached with this message. Please advise. Thanks.

Internal error: (java.lang.ClassNotFoundException) com.pty4j.PtyProcess
java.lang.ClassNotFoundException: com.pty4j.PtyProcess
