If a developer just commits a change deleting a file (and nothing else), the Common Back-end Scripts (CBS) will set the Return Code of the Build stage to 4 and stop the pipeline with a "No source changes detected" error, rather than continuing the pipeline run (e.g. with packaging of the deletions). This only happens when using the CBS (not with just zAppBuild), and may have to do with lines 523-526 near the end of the dbbBuild.sh script.
