I want to use sonar-cfamily-plugin-5.1.1.10386.jar in SonarQube-8.9 which has sonar-cfamily-plugin-6.20.2.38358.jar.
when i put sonar-cfamily-plugin-5.1.1.10386.jar to the extensions/plugins, i get a error:
Web server startup failed: Found a plugin ‘SonarCFamily’ in the directory ‘extensions\plugins’ with the same key [cpp] as a built-in feature ‘CFamily Code Quality and Security’. Please remove ‘extensions\plugins\sonar-cfamily-plugin-5.1.1.10386.jar’.
A build-wrapper, with a clean build, is a hard requirement on modern versions of SonarQube to get accurate and relevant analysis results. That’s why we removed the ability to bypass the build-wrapper: inaccurate results can be more dangerous (and annoying) than no results at all.
You may be interested to know that in SonarQube v9.1 it became possible to pass a compilation database to analysis instead of output from the build wrapper.
