title: Maven checksum failed
body: <p>I am working on a project that uses Maven as the build tool. I am using version 2.2.1 of the tool. Recently a coworker mentioned that he couldn't build the project because of checksum errors. I wasn't getting these errors so I deleted my local repository. Sure enough, I also got the checksum errors on the next attempt to build. We are using Archiva as our central repository, so I uploaded the jars again hoping to resolve the issue. No luck. What could be causing these errors and how do I resolve them?</p>
