# This file is meant to be included into a target to provide an action to
# repackage Java libraries and embed them into your own distribution.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'my_package_java',
#   'type': 'none',
#   'variables': {
#     'input_jar': 'path_to_your.jar',
#     'pattern': 'com.example.library.**',
#   },
#   'includes': ['path/to/this/gypi/file'],
# }
#
# The generated jar-file will be as defined in <(output_jar_file).
# Required variables:
#  input_jar - The source jar you want to jarjar.
#  pattern - a class name with optional wildcards.
#    ** will match against any valid class name substring.
#    To match a single package component (by excluding . from the match), a
#    single * may be used instead.
# Optional variables:
#  result_package - is a class name which can optionally reference the
#    substrings matched by the wildcards. A numbered reference is available for
#    every * or ** in the <pattern>, starting from left to right: @1, @2, etc.
#    A special @0 reference contains the entire matched class name.
#
# Note: This can not be used together with building a jar in your own target
# using src/build/java.gypi, since you will then have both jar files added to
# input_jars_paths through the use of the all_dependent_settings.
