I have a plugin that generates scala code from avro sources, it's been throwing this message

Users/seolh001/.cache/pants/setup/bootstrap-Darwin-x86_64/1.9.0rc1/lib/python2.7/site-packages/pants/task/simple_codegen_task.py:284: DeprecationWarning: DEPRECATED: SimpleCodegenTask.find_sources is deprecated. Subclasses should instead specify sources_globs and sources_exclude_globs. Class to update: ApacheAvroGen_gen_avro_scala. find_sources will be removed in version 1.10.0.dev0.

. I'm trying to address this by adding the

source_globs

variable.
