Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0-beta-2:sonar

We're using Sonar with jobs started by Jenkins.

Now we get this error when Jekins tries to run sonar-maven-plugin:

[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.0-beta-2:sonar (default-cli) on project SS_MGWTDMWebUI: Can not execute Sonar: PicoLifecycleException: method 'public void org.sonar.jpa.session.AbstractDatabaseConnector.start()', instance 'org.sonar.jpa.session.DriverDatabaseConnector@1a791f, java.lang.RuntimeException: wrapper: Cannot open connection to database: SQL driver not found com.mysql.jdbc.Driver -> [Help 1]

The error message states "SQL driver not found com.mysql.jdbc.Driver". Assuming your install is OK, can you check sonar.host.url does not end with '/' ?
