I am looking to make a new SonarQube plugin for the XQuery language. The current plugin is out of date and I cannot get it to compile, so I am planning to start from scratch. I already have and Antlr4 grammar and lexer at https://github.com/lcahlander/xqdoc. I would appreciate any tutorials for creating a Sonar plugin. I found the following link https://docs.sonarqube.org/display/DEV/Supporting+New+Languages, but I think that I need a tutorial or even a class maybe.
Any help that people can give me would be appreciated.
