I tried increasing memory but the problem still exists. I have used following options while running sonar: set SONAR_RUNNER_OPTS=-Xmx1024m -XX:MaxPermSize=512m
OK, after doing some more research I got it right. I had to do some setup, though.
sonar.skipPackageDesign=true
set SONAR_RUNNER_OPTS=-Xmx1536m -XX:MaxPermSize=512m
sonar.skipDesign=true
