Sonarqube is cool, as the generated results can not only be viewed via the web interface, but also via an plugin in IntelliJ or other Jetbrains IDEs. The installation is quite simple, you just need to download the latest plugin on this website: https://plugins.jetbrains.com/plugin/7238 and install it in the way described here: https://github.com/sonar-intellij-plugin/sonar-intellij-plugin. After that, you can easily hunt down and eliminate those errors :)!
