SENSITIVE DATA HAS BEEN REMOVED FROM THIS TICKET ACCORDING TO JFROG'S INTERNAL POLICY.
In the generic repository, the Set Me Up gives curl instructions for resolving and deploying artifacts. There is a space before the API key:
curl -H 'X-JFrog-Art-Api: RESTRICTED_TOKEN' -T <PATH_TO_FILE> "RESTRICTED_URL<TARGET_FILE_PATH>"
This works fine in a linux/OSX terminal. It fails in a Windows terminal. Space should be removed as that will work in both terminals.
