Nope, it's some problem of mapping between Ivy patterns and Maven repos that I don't know how to configure in Artifactory. Many of sbt plugins are hosted at http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/ which is an Ivy repo. The sbteclipse is hosted at Maven Central and for some reason Artifactory cannot serve it to sbt properly. I didn't have patience to dive into it.
