There are several Maven repository managers on the market, but the two most prominent and most powerful are without doubt Nexus and Artifactory. Both these products are open source, with commercial versions containing more advanced features. Both are fine products, with many similar features. In many cases, however, Nexus and Artifactory respond to similar user needs, but in quite different ways.

I recently installed Nexus onto an HP build server. While not particularly difficult, this installation did require a few extra steps. This article discusses how it was done - the approach can be applied for any O/S supported by Java Service Wrapper but not delivered out-of-the-box with Nexus, such as HP and AIX.
