So the Play framework people have just released 2.2.0 - a big release with lots of improvements . Migration isn't too hard - and I just checked it runs fine on CloudBees using the existing Play Clickstack:
Create a new play app, and run "dist"
note the zip generated from the previous step
bees app:deploy -t play2 target/universal/yourapp.zip
I will update clickstarts in the near future. (get the bees command line tool from here).
You can read the migration guide here .
Congratulations and keep up the good work Play team!
