title: Maven Could not find artifact after downloading from Nexus
body: <p>we have got a problem. I set up job on jenkins and while building a project it fetches artifacts from nexus. But even though it downloaded them job failed with artifacts could not be found. It happened only to artifacts we manually imported to the nexus.</p>
  
  <p>Any hints?</p>
