lastSuccessful promotion artifact url

Hi All, I'd like to know how to get an artifact of the lastSuccessful promotion independent of the project build number. For example, I figured I can get the artifact for a known project build by: /job/${project-name}/${build-number}/promotion/${promotion-name}/lastSuccessful/target/artifact/targ

jabber plugin - not sending when project created with jenkins-cli

I'm seeing an odd behavior with the Jabber Notifier plugin. When I create a project through the jenkins cli, I don't get any jabber notifications. If I then go to the "Configure" page through the UI and don't change *any* settings, simply click Save, then build, I start getting notifications.
