5# This file is meant to be included into a target to provide a rule to build
6# a JAR file for use on a host in a consistent manner.
7#
8# To use this, create a gyp target with the following form:
9# {
10#   'target_name': 'my_jar',
11#   'type': 'none',
12#   'variables': {
13#     'src_paths': [
14#       'path/to/directory',
15#       'path/to/other/directory',
16#       'path/to/individual_file.java',
17#       ...
18#     ],
19#   },
20#   'includes': [ 'path/to/this/gypi/file' ],
21# }
22#
23# Required variables:
24#   src_paths - A list of all paths containing java files that should be
25#     included in the jar. Paths can be either directories or files.
26# Optional/automatic variables:
27#   excluded_src_paths - A list of all paths that should be excluded from
28#     the jar.
29#   generated_src_dirs - Directories containing additional .java files
30#     generated at build time.
31#   input_jars_paths - A list of paths to the jars that should be included
32#     in the classpath.
33#   main_class - The class containing the main() function that should be called
34#     when running the jar file.
35#   jar_excluded_classes - A list of .class files that should be excluded
36#     from the jar.
