when I tried to compile the latest opencv with the contrib modules, it compiled successfully but install/sdk/java is missing. I did try to compile the v331 again and it compiles successfully and sdk/java exists without problem. I didn't change any steps between compiling these 2 versions though. Here's my cmake output.
