I'm trying to run one of the type safe activator projects in IntelliJ 13.1 with the latest Play 2 and Scala plugins.
I can run the project through the typesafe activator no problems but when I try to open the activator project via the build.sbt
file in IntelliJ it all seems to work until I try to run the thing via the Play 2 App run configuration. I get the following error;

Just running sbt run
from the command line in the project folder works fine. So there is some issue with the way the SBT project has been imported.
Android IDE - Java Suite A Java IDE is needed so developers can work for Android app development. We chose Eclipse, NetBeans, and IntelliJ IDE as the most popular ones. No matter which one of those you chose, all of them feature step by step tutorials for beginners and are powerful enough for the most advanced users.
You can also use play to fix it
cd /path/to/project
play
[project] idea with-sources=yes
And now you can right click on Application and run Play2 application.
