问题
I am using sonar plugin with jenkins. It always generates this error. It seems the plugin can't find the JDBC driver. I tried putting the JDBC driver in many possible places according to the many solutions I found in google, but it still generates this error.

I found the issue. It was in the sonar/conf/sonar.properties file (In sonarqube installation folder). Default url for database is wrong. I corrected it for mysql. Now it works fine. I spent days on this. Thanks TimHauschildt and SKempken.
