# Include this file in any target that is going to build java files.
#
# To use, create a target of the following form:
# {
#   'target_name': 'whatever',
#   'variables': {
#     'srcdirs': ['.', 'java'],
#   },
#   'includes': ['path/to/java.gypi'],
# }
# See below for more variables.
# To make any output jars include some loadable modules, set the 'jni_libs'
#   variable in 'direct_dependent_settings'. Making this easier causes lots of
#   recursion issues in gyp.
#   The dependency on these targets also has to be added manually.
