Jenkins-Sonar-Maven Integration Issue - maven

Question

I have been trying to integrate Sonar with our Jenkins continous Integration system. I have installed the Sonar-plugin for Jenkins and configured it(specified the DB, DB Username and password etc). I have also specified the sonar-maven-plugin version as 1.0-beta-2.
Along with this plugin configuration, I have added a build post-action to run Sonar on my maven projects. But everytime Jenkins tries to execute sonar:sonar goal it fails with the below error.
Please help me guys in resolving this problem.
Thanks

Answer 1

The problem clearly comes from your Nexus repository or from some specific configuration that you've made in your POM / settings.xml file / Jenkins settings. You should contact the guys who handle this "http://troop:8081" Nexus instance to know how to deal with your issue.
BTW, there's no need to force the version of the sonar-maven-plugin plugin: this will cause you only troubles.

Answer 2

what database are you using?, if it defaults to derby database then only connections from the localhost are allowed and thus sonar and jenkins should run in the same machine. If this is the problem i can give further guidance but in a nutshell either change the database, or change the derby connection properties or provide a ssh tunnel between sonar and jenkins machines.

Answer 3

Use in the your configuration sonar-maven-plugin 2.0-beta-1
instead sonar-maven-plugin:1.0-beta-2
