How to compiles samples of v3.0 beta with Eclipse?

I want to compile samples of v3.0 beta like TestCpp within Eclipse. The README.md file in ‘/cocos2d-x-3.0beta/samples/Cpp/TestCpp/’ is too old to work on cocos2d v3.0 beta. Where can I find any right guid or tutorial to help me compiling them with Eclipse? Most tutorials I found with Google are written for 2.x or 3.0 alpha0, the new SDK (v3.0 beta or alpha1) made a lot of changes like ‘Disabled CDT Builder on Eclipse’ but only provide a simple command-line compiles method:
### Build new project for android ### $ cd proj.android $ ./build_native.py
How to compiles them with Eclipse?

The apk I created with command-line always report crash.
