     - If set to `true` and an error is encountered, the failed file will be skipped and ignored and all other queued files will be attempted to be uploaded. There will be an artifact available for download at the end with everything excluding the file that failed to upload

+    - If this is set to a greater value than the retention settings allowed, the retention on artifacts will be reduced to match the max value allowed on the server, and the upload process will continue. An input of 0 assumes default retention value.
