I don't know if this helps but we are using a construct to do something
similar. We do something like this:
cmake_minimum_required(VERSION 2.8)
project( cplusplusapi_wrap )
MESSAGE("Please ensure the Environment variable JAVA_HOME has been set
correctly")
FIND_PACKAGE(SWIG REQUIRED)
INCLUDE(${SWIG_USE_FILE})
FIND_PACKAGE(Java REQUIRED)
FIND_PACKAGE(JNI REQUIRED)
INCLUDE_DIRECTORIES(${JAVA_INCLUDE_PATH})
INCLUDE_DIRECTORIES(${JAVA_INCLUDE_PATH2})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR})
SET(JAVA_RUNTIME2 $ENV{JAVA_HOME}/bin/java)
SET(JAVA_ARCHIVE2 $ENV{JAVA_HOME}/bin/jar)
SET(JAVA_COMPILE2 $ENV{JAVA_HOME}/bin/javac)
SET(CMAKE_SWIG_FLAGS -package cplusplusapi)
SET(SWIG_SOURCES
<various .i files>
/snip/
<end various .i files>
)
SET_SOURCE_FILES_PROPERTIES(${SWIG_SOURCES} PROPERTIES CPLUSPLUS ON)
#SET_SOURCE_FILES_PROPERTIES(${SWIG_SOURCES} PROPERTIES SWIG_FLAGS
"-includeall")
SWIG_ADD_MODULE(cplusplusapi_wrap Java ${SWIG_SOURCES})
SWIG_LINK_LIBRARIES(cplusplusapi_wrap SAIL <required libs go here>)
ADD_CUSTOM_COMMAND(TARGET cplusplusapi_wrap
POST_BUILD
COMMAND cmake -E echo "Compiling Java files..."
COMMAND cmake -E make_directory
${cplusplusapi_wrap_BINARY_DIR}/cplusplusapi
COMMAND ${JAVA_COMPILE2} *.java -d
${cplusplusapi_wrap_BINARY_DIR}
COMMAND cmake -E echo "Creating jar file..."
COMMAND ${JAVA_ARCHIVE2} cvf cplusplusapi_wrap.jar wrappedapi
)
One of the advantages of being disorderly is that one is constantly making
discoveries.

Subject: [CMake] making a jar from swig-generated jni library
To: "[email protected]" <[email protected]>

I am using swig in cmake to create a JNI wrapper around a C++ library.
Everything is working fine, however I would like to jar up all the
swig-generated java files. I'm not sure how to do it.
My project looks more or less like this:
cmake_minimum_required(VERSION 2.8)
project(mylib)
...<snip>...
# create library
include_directories(${CMAKE_SOURCE_DIR})
add_library(mylib mylib.cpp)
# create the jni wrapper
SET_SOURCE_FILES_PROPERTIES(mylib.i PROPERTIES CPLUSPLUS ON)
SWIG_ADD_MODULE(mylib-jni java mylib.i )
target_link_libraries(mylib-jni mylib)
project(mylib-jni Java)
# jar up the generated swig java sources
set(JAVA_SRCS ${CMAKE_SWIG_OUTDIR}/mylib.java
${CMAKE_SWIG_OUTDIR}/mylibJNI.java )
include_directories(${CMAKE_SWIG_OUTDIR})
add_library(mylib-java ${JAVA_SRCS})
However, this gives the error: 'Cannot find source file "mylib.java"'. Which
makes a kind of sense because mylib.java doesn't exist at cmake time. Do the
swig macros not mark the java files as "generated"? Am I doing something wrong?
Thanks,
aaron
