hi,
i found the problem, just in case anyone is interested. the problem was, that i
use "package first.second.third;" in my java-sources, so that the class files
are compiled to
${CMAKE_CURRENT_BINARY_DIR}/first/second/third/file.class and not to
${CMAKE_CURRENT_BINARY_DIR}/file.class, which is while the depend never found
the class files.
the remaining problem is to build the jar file on dependency of changes of the
class files. what i am currently trying is:
SET(MY_FILES File1 File2 File3)
SET(CLASS_FILES)
FOREACH(f ${MY_FILES})
LIST(APPEND CLASS_FILES
${CMAKE_CURRENT_BINARY_DIR}/${PACKAGE_PATH}/${f}.class)
ENDFOREACH(f ${MY_FILES})
ADD_CUSTOM_COMMAND(OUTPUT ${PROJECT_BINARY_DIR}/${JAR_DIR}/${JAR_FILE}
DEPENDS ${CLASS_FILES}
COMMAND ${CMAKE_COMMAND}
ARGS -E chdir ${CMAKE_CURRENT_BINARY_DIR} ${CMAKE_Java_ARCHIVE} cfm
${CMAKE_BINARY_DIR}/${JAR_DIR}/${JAR_FILE}
${CMAKE_CURRENT_SOURCE_DIR}/MANIFEST.MF org)
ADD_CUSTOM_TARGET(${JAR_FILE}
ALL
DEPENDS ${PROJECT_BINARY_DIR}/${JAR_DIR}/${JAR_FILE})
but the jar files is build every time i call make.
regards,
keyan
