| 11 | This is a helper file for the genproto_java action in protoc_java.gypi. |
| 12 | |
| 13 | It performs the following steps: |
| 14 | 1. Deletes all old sources (ensures deleted classes are not part of new jars). |
| 15 | 2. Creates source directory. |
| 16 | 3. Generates Java files using protoc. |
| 17 | 4. Creates a new stamp file. |
