I read https://docs.sonarqube.org/display/PLUG/Code+Coverage+by+Unit+Tests+for+Java+Project and used cobertura as my code coverage plugin then I see code coverage displays for small projects. When I check for a big project in sonar I just see code coverage as - that means its empty. In logs I could find that Cobertura report was not found at /.../coverage.xml path.

coverage.xml was not generated due to OutOfMemeryError:heapspace. Since my project is such a big project when I set heap memory to 2GB and cobertura plugin memory to 1.5GB sonar gets code coverage displayed.
