Description
（1）我用AS编译，然后发现要gradle.properties里面写很多跟“POM”有关的变量配置，然后应该怎么配置。
（2）我随便在gradle.properties下把所有变量补上之后，编译的时候，JniBitmapOperationLibray这个module会报错，错误信息如下：
C:\Users\Administrator\talk-android\library\JniBitmapOperationsLibrary\jni\do_not_delete_me_i_am_workaround.c:1:0: fatal error: opening dependency file C:\Users\Administrator\talk-android\library\JniBitmapOperationsLibrary\build\intermediates\ndk\release\obj/local/armeabi-v7a/objs/JniBitmapOperationsLibrary/C_\Users\Administrator\talk-android\library\JniBitmapOperationsLibrary\jni\do_not_delete_me_i_am_workaround.o.d: No such file or directory
（3）我把你们叫我不要删除的那个do_not_delete_me_i_am_workaround.c文件删除之后呢，准备clean一下project，然后就报出下面的错误：
Error:(540, 5) opening dependency file C:\Users\Administrator\talk-android\library\JniBitmapOperationsLibrary\build\intermediates\ndk\release\obj/local/armeabi-v7a/objs/JniBitmapOperationsLibrary/C_\Users\Administrator\talk-android\library\JniBitmapOperationsLibrary\jni\JniBitmapOperationsLibrary.o.d: No such file or directory。
