javascript - Play Framework and Require JS optimization fails -

i'm trying use requirejs play! framework 2.1.3, can't seem work in production. running play stage gives ioexception when optimizing requirejs.

i tried example on play framework docs: http://www.playframework.com/documentation/2.1.3/requirejs-support

i'm running project on windows machine. know stage , start tasks don't work on windows, requirejs optimization should work, right?

here's output of play stage:
