Now you tell me.

Play 2.0 Support is Now Part of the Scala Plugin

The key change we’d like to highlight is that the Scala and Play 2.0 plugins have merged together, so with IntelliJ IDEA 14 you don’t need to install them separately because Play 2.0 support is now a part of the Scala plugin. You still need to run IntelliJ IDEA Ultimate to enable Play 2.0 support though.
