title: SonarQube Findbugs "needs sources to be compiled"
body: <p>I am trying to get SonarQube findbugs working, but when I try to run it I get the error: &quot;Findbugs needs sources to be compiled. Please build project before executing sonar and check the location of compiled classes.&quot;</p>
  <p>sonar.sources is set to a folder with all of my src files and sonar.binaries is set to a folder with all of my class and jar files. This layout works with findbugs for one of my projects, but on the other I get the above error.</p>
  <p>How can I fix this, and is there a certain folder FindBugs needs classes/jars in to work?</p>
  <p>Thanks.</p>
