This example demonstrates how to write Custom Rules for SonarJava.

If you are using SonarQube 8.8 (latest release), use the following command to build it without any dependency to the current project status:

mvn clean install -f pom_SQ_8_8.xml

If you are using SonarQube 7.9 LTS, use this one:

mvn clean install -f pom_SQ_7_9_LTS.xml
