  <p>When i try to delete the .svn folder and run the sonar runner, it works fine. I have tried to ignore the svn files and svn folder, also i have tried to disable the blame option in the sonar but without any possible outcome.</p>
  
  <p>Which is the right way to do this ??</p>
  
  <p>its not mentioned anywhere. I want to eliminate the error caused by blame(svn) but I don't want to delete the ".svn" folder before the analysis(which is the only way i'm able to get it working)</p>
