Build apk failed

I have JavaScript project. Project compiles without any problems. But I trying build apk file and I have error message like this:

Python: 2.7.8
Java: 1.7.0.67
Apache ant: 1.9.4
Android NDK: r9
Cocos2d-js: 3.0

How can I fix this?

Please use r9d to build apk.
BTW, cocos2d-js 3.1 and Cocos Code IDE 1.0.1 have been released!

Thanks. I already fixed my problem. The main problem was russian letters in directory path (user directory).
