Upload-artifact: Upload should fail if no files are found

[themakshter]

As mentioned in your comment in #47, I think it would be good to have the fail-if-no-files-uploaded option. I know that a warning is posted, but I do believe that such a case is cause for failure rather than a warning in some cases as the upload containing files is a required check and not just a warning.

Is there really not even an option to force a failure if there are no files found for uploading?

I think there are plenty alternative ways of handling an upload task not finding files that wouldn't be there; namely that you do a conditional check for the job to be run in the first place. But there are no ways to declare that the job fails if its intended task doesn't actually do anything?
