Sets the timestamp of the xslt generation. This mojo should be run after other executions of the xslt generator. It takes the prepared timestamp file and sets the timestamp based on it.

By default runs in process-resources phase, if needed, customize the phase as required. Generally should be run as the last execution of the generator in the build (eg. if generate-test-resources phase is the last one you use the generator in, finalize it in this phase).
