Can not find Java folder in OpenCV build

I have built OpenCV for android on Windows using CMAKE, MINGW and NVIDIA Android NDK. After I make it and make install it, I found the following folders:

install:
 -apk:
 -sdk:
   --etc
   --native

there is no java folder inside the sdk folder. What did I miss?

there is no java folder inside the sdk folder. libopencv_java3.so is also mssing. What did I miss?
