+#
+# This command creates a <TARGET_NAME>.jar. It compiles the given source
+# files (SRC) and adds the given resource files (RCS) to the jar file.
+# If only resource files are given then just a jar file is created.
+#
+# Additional instructions:
+#   To add compile flags to the target you can set these flags with
+#   the following variable:
+#
+#       set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
+#
+#   To add a path or a jar file to the class path you can do this

+#
+#       set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
+#
+#   To use a different output name for the target you can set it with:
+#
+#       set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
+#       add_jar(foobar foobar.java)
+#
+#   To add a VERSION to the target output name you can set it using
+#   CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
+#   shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
+#   pointing to the jar with the version information.
+#
+#       set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
+#       add_jar(shibboleet shibbotleet.java)
+#
+#    If the target is a JNI library, utilize the following commands to
+#    create a JNI symbolic link:
+#
+#       set(CMAKE_JNI_TARGET TRUE)
+#       set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
+#       add_jar(shibboleet shibbotleet.java)
+#       install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
+#       install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
+#
+#    If a single target needs to produce more than one jar from its
+#    java source code, to prevent the accumulation of duplicate class
+#    files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
+#    to calling the add_jar() function:
+#
+#       set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
+#       add_jar(foo foo.java)
+#
+#       set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
+#       add_jar(bar bar.java)
+#
+# Target Properties:
+#   The add_jar() functions sets some target properties. You can get these

+#                      This is used by install_jni_symlink().
+#   JAR_FILE           The location of the jar file so that you can include
+#                      it.
+#   CLASS_DIR          The directory where the class files can be found. For
