"""Generate java source files from protobufs
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
protoc_java.py {protoc} {proto_path} {java_out} {stamp_file} {proto_files}
|
||
|
|
|
||
|
|
This is a helper file for the genproto_java action in protoc_java.gypi.
|
||
|
|
|
||
|
|
It performs the following steps:
|
||
|
|
1. Deletes all old sources (ensures deleted classes are not part of new jars).
|
||
|
|
2. Creates source directory.
|
||
|
|
3. Generates Java files using protoc.
|
||
|
|
4. Creates a new stamp file.
