title: Unable to connect Sonar Eclipse Plugin to Sonar Server
body: <p>I have installed the latest version on the Sonar Eclipse Plugin on an Eclipse Juno 3.8. I am desperatly trying to connect the plugin to our running instance of Sonar. I'm behind a NTLM v2 Proxy. Hereunder, details of my configuration and  my attempts.</p>
  
  <p>Versions of products :</p>
  
  <ul>
  <li>Eclipse 3.8,</li>
  <li>Sonar Eclipse Plugin (Java Analyzer &amp; m2e Connector) 3.2.0.20130627-1142-RELEASE,</li>
  <li>SonarQube Server 3.7 (running on <code>http://source01:9000</code>, in the LAN, not behind the proxy, direct connection possible).</li>
  </ul>
  
  <p>Trying to access with the following proxy configurations with an without http_proxy variable in the configuration:</p>
  
  <ul>
  <li>direct with http_proxy : failure,</li>
  <li>direct without http_proxy : success (but unable to use other Eclipse feature accessing Internet like the Marketplace),</li>
  <li>native (with or without http_proxy) : failure,</li>
  <li>manual (with or without http_proxy): failure.</li>
  </ul>
  
  <p>I systematically got org.apache.http.conn.ConnectTimeoutException in the logs (trying to access <code>http://source01:9000/api/authentication/validate</code> which work in a browser).</p>
  
  <p>No more idea on what to test.</p>
