SonarQube integration with Jenkins

Question

I am trying to integrate SonarQube runner in my build process. My build steps consists of an ant build and sonar-runner task. I have attached the Screenshots later. I am getting an error stating "

Unable to determine database dialect to use within sonar with dialect null jdbc url localhost Build step 'Invoke Standalone SonarQube Analysis' marked build as failure

Inside my Jenkins->Manage Jenkins->Configure System , I have configured the sonar qube section as shown in the screenshot below-

Here is the screenshot of my build config-

I am not getting the clue on how to debug ? Any suggestion ?

Here are the version details-

SonarQube Runner 2.4

Sonar Version 5.1

Answer 1

Can you double check if you are specifying the correct JDBC URL. In the screenshot attached, SonarQube is configured with datasource URL as 'localhost'.

The stacktrace again says you do not have a database dialect specified. This can be specified in the sonar properties file.

Answer 2

I realised, what was wrong here. I had added incorrect database dialect in my jenkins configuration (Jenkins->Manage Jenkins->Configure System). See the screenshot. Earlier i had used

localhost

instead of

jdbc:mysql://localhost:3306/sonar?autoReconnect=true&useUnicode=true&characterEncoding=utf8
