# Copyright (c) 2012 The Chromium Authors. All rights reserved.
# Use of this source code is governed by a BSD-style license that can be
# found in the LICENSE file.
# This file is meant to be included into a target to provide a rule
# to build Java in a consistent manner.
#
# To use this, create a gyp target with the following form:
# {
# 'target_name': 'my-package_java',
# 'type': 'none',
# 'variables': {
# 'package_name': 'my-package',
# 'java_in_dir': 'path/to/package/root',
# },
# 'includes': ['path/to/this/gypi/file'],
# }
#
# The generated jar-file will be:
# <(PRODUCT_DIR)/lib.java/chromium_<(package_name).jar
# Required variables:
# package_name - Used to name the intermediate output directory and in the
# names of some output files.
# java_in_dir - The top-level java directory. The src should be in
# <java_in_dir>/src.
# Optional/automatic variables:
# additional_input_paths - These paths will be included in the 'inputs' list to
# ensure that this target is rebuilt when one of these paths changes.
# additional_src_dirs - Additional directories with .java files to be compiled
# and included in the output of this target.
# generated_src_dirs - Same as additional_src_dirs except used for .java files
# that are generated at build time. This should be set automatically by a
# target's dependencies. The .java files in these directories are not
# included in the 'inputs' list (unlike additional_src_dirs).
# input_jars_paths - The path to jars to be included in the classpath. This
# should be filled automatically by depending on the appropriate targets.
# javac_includes - A list of specific files to include. This is by default
# empty, which leads to inclusion of all files specified. May include
# wildcard, and supports '**/' for recursive path wildcards, ie.:
# '**/MyFileRegardlessOfDirectory.java', '**/IncludedPrefix*.java'.
# has_java_resources - Set to 1 if the java target contains an
# Android-compatible resources folder named res. If 1, R_package and
# R_package_relpath must also be set.
# R_package - The java package in which the R class (which maps resources to
# integer IDs) should be generated, e.g. org.chromium.content.
# R_package_relpath - Same as R_package, but replace each '.' with '/'.
