Can Artifactory be used as "SCM" or source in Jenkins to trigger the builds on an particular artifact deploy?
Don't see (or miss it) anything similar in the Artifactory Jenkis plugin description (and on Jenkins side)
This could be needed for instance if there is only access to the Artifactory repository and not to the SCM with code the binaries are coming from.
Such functionality looks to be availble for Nexus (via nexus-webhook-plugin). Hard to believe that this feature is missing for Artifactory.
Now you can use Enable Artifactory trigger in a newer version.
Go to Build Triggers and check the Enable Artifactory trigger checkbox.
