Where is the actual JSB file in IDE debug environment

Hi,

I’m using cocos IDE with JS 3.0
I didn’t need to modify the jsb function until today.
I can’t figure out where to modify the actual code.
I modified myProject/frameworks/js-bindings/cocos2d-x/cocos/xxx.cpp, it doesn’t affect the debug run
I modified myProject/frameworks/js-bindings/cocos2d-x/bindings/auto/jsb_cocos2dx_auto.cpp, also doesn’t affect the debug runs.
I even delete the whole frameworks folder, debug run still runs fine.

Where is the actual file it refer to when running in debug mode?

This is under Mac OSX + JS 3.0rc2
