  <p>What i've tried:</p>
  
  <p>Updating the packages in the plugins folder, to the latest from <a href="http://docs.codehaus.org/display/SONAR/Java+Ecosystem">Sonar Ecosystem</a> no they were all sonar-*-1.4.jar </p>
  
  <p>How can i update the findbugs and java plugin without accessing sonar?</p>
