SonarQube migration issue- Jenkins Using old URL

SonarQube migration issue- Jenkins Using old URL

I recently migrated a SonarQube server from one server to another in order to scale out the service to our dev team. All went well until builds failed due to them looking at both the old and new server URLs for the Sonar results and so I’m writing some notes here to help me (and others) out in the future if I hit this again.

I installed the same version of SonarQube on the new application server that is on the old server. The database was not being moved, just the application server (the server with the Sonar service running).

After installation I ensured that the same custom config settings were made onthe new server as had been made on the old server, and ensured that the same plugins were in place. I then stopped the Sonar service on the old server and started the service on the old box.

Once Sonar was confirmed to be up and running and connecting to the Database and showing the project dashboards I updated the Jenkins server configuration to point to the new box. All looked good so I ran a build, and then got this (log truncated)….

java.lang.IllegalStateException:
Fail to request http://OLDSERVER/api/ce/task?id=3423
at org.sonarqube.ws.client.HttpConnector.doCall(HttpConnector.java:212)

Bizarely the Jenkins build has managed to use both the new Sonar URL and the old one.The upload was successfull to the new server but some of the links for the resport point to the old server. Also the Quality Gate check whcih validates that the Sonar Quality Gate was successfull has tried to read the report on the OLD server and therefore failed as its not there (because its on the new sonar URL).

After checking Jenkins for any reference to the old Sonar server and restarting the service to clear any caches I was still getting the error. Eventually I ran a Jenkins build and interactively peeked into the Jenkins workspace on the Jenkins Slave and in there is an auto generated file containing lots of Sonar config settings. This file, SonarQubeAnalysisConfig.xml, is created during the Jenkins build initialisation stage. In the file I found references to the new Sonar URL but also this property pointing to the old URL:

  sonar.core.serverBaseURL  

This value is set in SonarQube configuration and is not dynamic and so will not be updated when you migrate the server or change the server URL/port. To change it open SonarQube > Administration > Configuration > General and change Server base URL to your new URL (e.g. http://yourhost.yourdomain/sonar). It says that this value is used to create links in emails etc but it in reality is also used to integate results.
