Nexus - my next Maven repository manager
The lads at Sonatype have just released a new Maven Repository Manager, called Nexus.
According to the Nexus web site, this is a rewrite of the deceased Proximity repository manager. I was never too fussed with Proximity, but Nexus is very cool.
There are other a few other Maven repository managers out there. Artifactory has a very slick AJAX-style user interface, but to do any serious configuration changes, you need to dive into those XML configuration files (CruiseControl, anyone?). Archiva is powerful, but a tad hard to configure.
Nexus comes bundled with Jetty, so you can run it directly from the command line, and be up and running very quickly.
And it has a very slick AJAXy interface, and pretty much everything can be configured online, from the repositories to network configuration details such as the enterprise proxy configuration. In particular, setting up a proxy to a public repository is as easy as I've seen on any Maven Repository Manager.
For more details, Tim O'Brien has written an excellent introduction to Nexus here.
