MODJAVA_VER?=

# Based on the MODJAVA_VER, NO_BUILD and MACHINE_ARCH, the following
# things will be setup:
#
#   ONLY_FOR_ARCHS if not already set.
#   BUILD_DEPENDS on a jdk (only if not NO_BUILD)
#   JAVA_HOME to pass on to the port build
#   RUN_DEPENDS for all jdk's that can run the port.
#   MODJAVA_RUN_DEPENDS with same value as RUN_DEPENDS
#   to assist with multipackages.
#
# NOTE: All source built java ports must properly set javac -source and
# -target build arguments. Depending on the architecture an older level
# port may be built by a newer jdk. The JAVA_HOME variable points to the
# build jdk not the default RUN_DEPEND jdk, so it should not be used to
# set a default jdk to run with. The javaPathHelper port should be used
# to set the default JAVA_HOME or JAVACMD vars for a package.
