# Build support for guice within the Android Open Source Project
# See https://source.android.com/source/building.html for more information
#

# Factored-out implementation of calling munge to post-process guice java files.
#
# Arguments:
#  (Constant)
#    munge_host_jar = Path to munge-host.jar (built by munge-host rule)
#    munge_zip_location = Path to lib/build/munge.jar source archive
#  (Varying)
#    munge_src_arguments = List of files that need to be munged
#    guice_munge_flags = List of flags to pass to munge (e.g. guice_munge_flags := -DNO_AOP)
#

LOCAL_MODULE_CLASS := JAVA_LIBRARIES
# Run munge over every single java file.
intermediates:= $(local-generated-sources-dir)
GEN := $(addprefix $(intermediates)/, $(munge_src_arguments)) # List of all files that need to be munged.
