示例1: finishJob

// forever until it finally gets a successfull response from the API.

		if err != nil {
			// If the API returns with a 422, that means that we
			// succesfully tried to finish the job, but Buildkite
			// rejected the finish for some reason. This can
			// sometimes mean that Buildkite has cancelled the job
			// before we get a chance to send the final API call
			// (maybe this agent took too long to kill the
			// process). In that case, we don't want to keep trying
			// to finish the job forever so we'll just bail out and
			// go find some more work to do.
