title: The SonarQube Post-build Action is deprecated
body: <p>Using Jenkins 1.642.2 for code analysis with SonarQube 5.6.1 for all my maven projects.</p>
  
  <p>When I use maven goal sonar:sonar they take more time to analyse files (more than 7 seconds by file) :</p>
  
  <pre><code>[INFO] Sensor SCM Sensor
  [INFO] SCM provider for this project is: svn
  [INFO] 1079 files to be analyzed
  [INFO]

  [INFO] 3/1079 files analyzed
  [INFO] 4/1079 files analyzed
  [INFO] 5/1079 files analyzed
  </code></pre>
  
  <p>When I use the SonarQube Scanner with this config :</p>

  <p>then i have this error :</p>

  <p>My settings file :</p>
  
  <pre><code>&lt;profile&gt;
          &lt;id&gt;sonar&lt;/id&gt;
          &lt;activation&gt;

          &lt;/activation&gt;

              &lt;/sonar.jdbc.url&gt;
              &lt;sonar.jdbc.username&gt;sonar&lt;/sonar.jdbc.username&gt;

              &lt;/sonar.host.url&gt;
          &lt;/properties&gt;
      &lt;/profile&gt;
  </code></pre>
  
  <p>Any idea to solve this problem because i have a problem to understand the new sonarqube use</p>
  
  <p>i must make a sonar-project.properties file for the maven project?</p>
