When using the Artifactory plugin, the promoted-builds plugin, version 3.3, is not compatible. Having it installed results in being unable to configure artifactory plugin settings in job configurations. Specifically the target repository drop down field will not populate, even after a successful api call to retrieve the available repositories. Also, the upload URL field is duplicated on the screen.
Downgrading promoted-builds plugin to version 3.2 resolved this problem.
This happened with multiple recent artifactory plugin versions. Same behavior each time.
