  <p>I thought it was because the JavaSquidSensor is no longer needed for SonarQube 5.1 so i removed it:</p>

  <p>Above is my plugins folder. I removed the <code>sonar-squid-java-plugin-2.2.1</code> but I am still getting the same error.  </p>
  
  <p>Any ideas on why this is still happening? Running Sonar on Windows-64</p>
