play 2.2.6 built with Scala 2.10.3 (running Java 1.8.0_05), http://www.playframework.com

This is not a play application!

Use `play new` to create a new Play application in the current directory,
or go to an existing application and launch the development console using `play`.

You have conflict with installed scala application, you can use aplay or paplay instead.
