Sonar runner (ubuntu) execution failed: com.mysql.jdbc.Driver

Question

I've recently installed SONAR on a Vagrant box running UBUNTU. Sonar service run fine, but when I try to run the sonar-runner I get an error related to jdbc connector.

I configured sonar to run with mysql database by changing the file "sonar-runner.properties":

sonar.jdbc.url=jdbc:mysql://127.0.0.1:3306/sonar?seUnicode=true&characterEncoding=utf8
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar

When trying to start sonar-runner i get the following output:

$ sudo sonar-runner start -e

ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.

From my undertanding the jdbc driver is not found. I thought that during initalisation sonar-runner will get the required jar (like it does for other libraries).

I tried to "sudo apt-get install libmysql-java" but still get the same error message. If that's the right thing to do (which I doubt) I should maybe add the jar to my classpath, but I'm don't know where that jar is actually downloaded and how to add it to the classpath.

Any idea on how to get that solved?

Thanks!!

Answer 1

I was looking at the wrong place! Issue was not comming from the runner but from SONAR itself. I had to change de sonar config file '/opt/sonar' and restart it. In the setting page I now can see that sonar is running on mysql. I'm facing a other issue with the runner, but it is not related to the issue above.

So basicaly make sure both SONAR and SONAR-RUNNER are configured to work with mysql.

Answer 2

I had the same issue. Issue was that mysql JDBC connector was not in my bash_profile. So i add on .bash_profile :

export jdbc mysql connector to classpath

    export CLASSPATH=${HOME}/sonar/mysql-connector-java-5.1.23/mysql-connector-java-5.1.23-bin.jar:$CLASSPATH

Hope it could help
