title: Jenkins fails due to NoClassDefFoundError: org/sonatype/aether/version/VersionConstraint
body: <p>I'm attempting to set up Jenkins on my server but after building the job things turn south. You can view the console here: <a href="http://ci.lolmewn.nl/job/AcceptRules/4/console" rel="nofollow noreferrer">http://ci.lolmewn.nl/job/AcceptRules/4/console</a></p>
  
  <p>At first I thought this was an issue with me not having configured my nexus yet (since the error contained sonatype, the makers of Nexus), but when I built one of my jobs without it having repository pushing, this still happened.</p>
  
  <p>Any clues? I see there's a question like mine, unanswered however, <a href="https://stackoverflow.com/questions/18169415/java-lang-classnotfoundexception-org-sonatype-aether-version-invalidversionspec">here</a></p>
