org/sonar/batch/bootstrapper/EnvironmentInformation has been compiled by a more recent version of the Java Runtime

Question

I'm trying to integrate SonarQube scanner into a TeamCity build configuration. I have installed the Sonar Runner plugin and set the build step to use scanner version 4.2.0, and run a build with the step enabled. Sonar Runner version is 2020.1-12 provided by JetBrains.

When the build reaches the step, it fails with

 ERROR: Error during SonarQube Scanner execution

What am I missing here?

Answer 1

I resolved this by updating the buildAgent.properties file, adding the line

env.TEAMCITY_JRE=C\:\\Program Files\\Java\\jdk-23

Now in TeamCity, on my SonarRunner step, I see the following

I don't know why adding it to the agent configuration means it shows in the build configuration step, but without the line present, it wasn't working.
