GC overhead Limit exceeded while running sonar runner

Question

I am getting OutOfMemoryException while performing sonar analysis on my project. Below is the stack trace:

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

Answer 1

OK, after doing some more research I got it right. I had to do some setup, though.

1. Skip the package design analysis, sonar.skipPackageDesign=true
2. Remove the entries for lib/test directory in your project's properties file
3. Give some more memory set SONAR_RUNNER_OPTS=-Xmx1536m -XX:MaxPermSize=512m
4. Optionally you can disable design analysis by using sonar.skipDesign=true
5. Restart SonarQube services and you should be good now :)
