Empower Hudson with Artifactory - Track and Replay Your Build Artifacts
Interesting post that introduces Hudson-Artifactory integration:
Artifactory is definitely more than just Maven repository manager, the option of having build info together with deployed artifacts can be very useful.
Although there are differences between the open source version and the commercial version of Build Integration in Artifactory, we should consider Artifactory as a replacement for Nexus.
There is also a wiki page for Artifactory Build Integration: wiki.jfrog.org/confluence/display/RTF/Build+Integration
