I want to use SonarQube for PL/SQL. I downloaded the plugin from the SonarQube Site and placed it into $SONARQUBE_HOME/extensions/plugins. Then I restarted the SonarQube Server but it didn't start up. When I removed the plugin it was working.
How can I resolve this issue?
The PL/SQL language is supported as part of the SonarSource Developer Edition, which is a commercial package for which you need a license.
This is why if you install it manually, this will not work.
