title: Maven build failing on dependencies
body: <p>I have a local artefact repository which my maven settings are pointed at but for some reason this doesn't seem to hit it, and fails all the time when trying to do an install.
  I can access the url directly in my browser and can also access the maven repo via browser.
  I can also ping both.</p>
  
  <p>Any ideas why it keeps failing?
  Stack trace below</p>
  
  <p>Cheers,</p>
