How to get play! framework running in MSYS bash

Question

I can’t use play! framework from a MSYS shell (as used in Git on Windows).

Error during sbt execution: Could not find configuration file
'c:/Dev/Prg/Play/framework/sbt/play.boot.properties'.  Searched:
        file:/C:/Users/Paul/
        file:/C:/Users/Paul/
        file:/C:/Dev/Prg/Play/framework/sbt/

Is there a way to get this running?
