All, I am attempting to build OpenCV 2.4.4a. I have built OpenCV many times but it seems like the newest distribution has malfunctioning build code.

My compilation fails at:

[ 87%] Build Java tests
Buildfile: .../OpenCV-2.4.4/release/modules/java/test/.build/build.xml

build:

compile:
    [javac] Compiling 104 source files to .../OpenCV-2.4.4/release/modules/java/test/.build/build/classes

BUILD FAILED
.../OpenCV-2.4.4/release/modules/java/test/.build/build.xml:55: The following error occurred while executing this line:
.../OpenCV-2.4.4/release/modules/java/test/.build/build.xml:19: .../OpenCV-2.4.4/release/modules/java/test/.build/lib does not exist.

I have tried finding information on how to disable this java library, I have no use for it. Can anyone offer some advice?

This problem is incredibly unnerving as OpenCV is a very large library that doesn't build very quickly. I am attempting to reuse builds but I continuously have to recompile a few modules only to return to this problem. I have tried many flags.

Very Active Q & A ... Anyways my solution was to blow away the source directory in modules/java with a nice little

rm -rf java

Seriously...

try to use this option -DBUILD_opencv_java=OFF in order to close the new java integration till to fix the problem in a newer version. According to the following link seems to work. http://answers.opencv.org/question/7623/opencv-244-beta-java-test-error/

That didn't work for me, as the flag does not exist in any of the CMake files.

i noticed that it does not exist in any of the CMake files but it worked for me. However, in the new updated version v2.4.5 the problem seems to be solved, so you do not need to use this option.
