# This file is meant to be included into a target to provide a rule to build
# a JAR file for use on a host in a consistent manner. If a main class is
# specified, this file will also generate an executable to run the jar in the
# output folder's /bin/ directory.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'my_jar',
#   'type': 'none',
#   'variables': {
#     'src_paths': [
#       'path/to/directory',
#       'path/to/other/directory',
#       'path/to/individual_file.java',
#       ...
#     ],
#   },
#   'includes': [ 'path/to/this/gypi/file' ],
# }
#
# Required variables:
#   src_paths - A list of all paths containing java files that should be
#     included in the jar. Paths can be either directories or files.
# Optional/automatic variables:
#   excluded_src_paths - A list of all paths that should be excluded from
#     the jar.
#   generated_src_dirs - Directories containing additional .java files
#     generated at build time.
#   input_jars_paths - A list of paths to the jars that should be included
#     in the classpath.
#   main_class - The class containing the main() function that should be called
#     when running the jar file.
#   jar_excluded_classes - A list of .class files that should be excluded
#     from the jar.
