problem when integrating project from 2.0.2 to 2.0.3

Recently I’m integrating a project from 2.0.2 to 2.0.3. I have finished it in XCode, and problem happens when trying it in Eclipse for Android version.

First it runs correctly , after I changed some default properties. and after I copied all codes which could work in IOS, it reports following exception:
_
make: * No rule to make target `jni/helloworld/main.cpp’, needed by `obj/local/armeabi/objs-debug/game_shared/helloworld/main.o’. Stop. C/C++ Problem_

all I did is to change some .mm files back to .cpp, and copied LOCAL_SRC_FILES in Android.mk file. I’m not sure how it comes to this exception.

just found the reason about this problem.

in 2.0.2, the main.cpp in jni is under helloworld folder, while in 2.0.3 it renamed to hellocpp… surely it crashed when i copied LOCAL_SRC_FILES property from 2.0.2 to 2.0.3…
