How to fix "The following languages have no built-in quality profiles" since SQ 7.2.1 with custom plugin

Question

I develop custom SQ plugins for several SQ versions. I am facing a issue since SQ 7.2.1. On SQ startup, le web.log file tells

-normal Register rules
-start [o.s.s.q.BuiltInQProfileRepositoryImpl] Load quality profiles
-stops with the following error : [o.s.s.p.Platform] Background initialization failed. Stopping SonarQube
-java.lang.IllegalStateException: The following languages have no built-in quality profiles: csh

Note csh is my language name

The SQ startup is fine for version 7.1 and previous with my plugin

How to configure the custom plugin to solve this issue ? Thanks for your help

Answer 1

You have to implement the BuiltInQualityProfilesDefinition extension point to list rules that should be enabled by default for your language.

Prior to SonarQube 7.2 it was not mandatory to declare a built in quality profile for each language, but it was causing some bugs. See https://jira.sonarsource.com/browse/SONAR-10283
