Error when compiling Cocos2D-JS tutorial

[ChStark]

Hi dev, Im starting with cocos2d-js and I am following the tutorial, but when I try to build in release mode it fails.

If I run
cocos compile --platform android --mode release
I get

Error running command, return code: 2.

Everything works fine when I compile in debug mode, any Idea why ?

Thanks in advance

check your android.mk from /Users/"yourname"/Documents/GitHub/yourproject/nameAnd/proj.android-studio/app/jni/Android.mk
did you already write the reference class there?
