There are two ways to extend code rules: But Java only supports mode 1

1. Writing coding rules using Java via a SonarQube plugin

2. Adding XPath rules directly through the SonarQube Web interface

Writing coding rules in Java is a six-step process:

• Create a SonarQube plugin.
• Put a dependency on the API of the language plugin for which is writing coding rules.
• Create as many custom rules as required
• Generate the SonarQube plugin (jar file)
• Place this jar file in the sonarqube_home/extensions/plugins directory
• Restart SonarQube Server
