Summary0006960: Cmake 2.4.8 No way to specify Main-Class in manifest when creating jar files (ADD_EXECUTABLE with java support?)
DescriptionWhile using CMake (2.4.8) on darwin (10.4 ppc)

There is no way I could discover in the man page to specify the entry point
for a jar file.

ADD_EXECUTABLE: does not work with java,

ADD_LIBRARY: creates a jar file, no way to specify the value of Main-Class or
a manifest file to be supplied to the jar command.

I am using 2.6.4 and the problem is still there. (not sure about 2.8) What we need is just to be able to specify an entry point.

- CMAKE_Java_CREATE_STATIC_LIBRARY: <CMAKE_Java_ARCHIVE> -cf <TARGET> -C <OBJECT_DIR> ${class_files_mask}
+ CMAKE_Java_CREATE_STATIC_LIBRARY: <CMAKE_Java_ARCHIVE> -cfe <TARGET> org.my.special.java.class.MyEntryPoint -C <OBJECT_DIR> ${class_files_mask}

Example:
/usr/bin/jar -cfe myprog.jar org.my.special.java.class.MyEntryPoint -C CMakeFiles/myprog.dir .

Or alternatively, we could use ADD_LIBRARY and then ADD_CUSTOM_COMMAND to update JAR:

MACRO(MACRO_MAKE_JAR_EXECUTABLE VAR_TARGET VAR_ENTRY)
  GET_TARGET_PROPERTY(VAR_LOCATION "${VAR_TARGET}" LOCATION)
  ADD_CUSTOM_COMMAND(TARGET ${VAR_TARGET} POST_BUILD COMMAND ${CMAKE_Java_ARCHIVE} ufe ${VAR_LOCATION} ${VAR_ENTRY} COMMENT "Creating JAR entry point.")
  UNSET(VAR_LOCATION)
ENDMACRO()

SET (MY_ENTRY "path.to.my.Main")

ADD_LIBRARY(MyJavaLibrary ${MY_SRCS})
MACRO_MAKE_JAR_EXECUTABLE(MyJavaLibrary "${MY_ENTRY}")
