Problem with Jenkins + SonarQube

SonarQube Server / Community Build Plugin Development

The sonar.java.jdkHome property is only some extra information for the analysis.
But the analysis itself has to run with Java 17, when in your case it runs with Java 8 (class version 52.0)

You may use 2 Maven CLI commands like that, i.e.

this may run with Java 8 for compilation

withMaven(jdk: ..., maven: ..., globalMavenSettingsConfig: ...) {
  sh 'mvn clean install'
}

but this has to run with Java 17 and nodejs 20 is recommended

nodejs(configId: ..., nodeJSInstallationName: 'nodejs-20') {
  withSonarQubeEnv(...) {
    withMaven(jdk: 'java-17-openjdk', maven: ..., globalMavenSettingsConfig: ...) {
      sh 'mvn sonar:sonar'
    }
  }
}
