             Summary: [Gandiva] Make it possible to compile gandiva without JNI
                 Key: ARROW-3589
                 URL: https://issues.apache.org/jira/browse/ARROW-3589
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Philipp Moritz


When trying to compile arrow with
{code:java}
cmake -DARROW_PYTHON=on -DARROW_GANDIVA=on -DARROW_PLASMA=on ..{code}
I'm seeing the following error right now:
{code:java}
CMake Error at /home/ubuntu/anaconda3/share/cmake-3.12/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

  Could NOT find JNI (missing: JAVA_AWT_LIBRARY JAVA_JVM_LIBRARY

  JAVA_INCLUDE_PATH JAVA_INCLUDE_PATH2 JAVA_AWT_INCLUDE_PATH)

  src/gandiva/jni/CMakeLists.txt:21 (find_package)





-- Configuring incomplete, errors occurred{code}
It should be possible to compile the C++ gandiva code without JNI bindings, how about we introduce a new flag "-DARROW_GANDIVA_JAVA=off" (which could be on by default if desired).
