Hello,
 
I am not sure if this is the right place for it but I am struggling with the following matter.
I configured a Jenkins Multibranch pipeline which runs a SonarQube analysis against my whole code (it consists in a Maven project and a React application).
Here is the sample of code of my Jenkins pipeline for running it:

stage('SonarQube Analysis') {
  environment {
    scannerHome = tool 'main-sonarqube-scanner'
  }
  steps {
    withSonarQubeEnv(installationName: "SonarQube-MYPROJ") {
      sh '${scannerHome}/bin/sonar-scanner -Dsonar.projectName=wave-other-branches -Dsonar.projectKey=MYPROJ -Dproject.settings=sonar-project.properties'
  }
}}

stage("Quality Gate") {
  steps {
    timeout(time: 2, unit: 'MINUTES') {
      waitForQualityGate abortPipeline: true
  }
}}

 
Here is the content of my sonar-project.properties:
 

sonar.sourceEncoding=UTF-8
sonar.cfamily.threads=4
sonar.java.skipUnchanged=true
sonar.language=java
sonar.exclusions=scripts/**
sonar.java.binaries=**/*
sonar.java.libraries=**/target/*.jar
sonar.python.version=3
sonar.filesize.limit=120

 
 
From Manage Jenkins > Tools, I configured a SonarQube Scanner with the name "main-sonarqube-scanner", installed automatically from Maven Central with version 4.8.0.2856.
From Manage Jenkins > System, I configured a SonarQube server with the name "SonarQube-MYPROJ" with the URL from our SonarQube server specified and Server authentication token.
 
Everything works perfectly fine, the analysis is run and I successfully see the Quality Gate result when looking at a job.
 
However, I noticed some errors in the Jenkins Logs:
sept. 18, 2023 2:44:26 PM INFOS hudson.plugins.sonar.client.SQProjectResolver resolve
Invalid installation name: MYPROJ
 
I added a Log Recorder for Sonar and everytime a new analysis is run there are such following errors:
sept. 18, 2023 2:42:53 PM PRÉCIS hudson.plugins.sonar{{{}Error fetching project information: Error 404 on http://[sonarqube-server-ip]:8090/api/qualitygates/project_status?analysisId=AYkInrGTShl6_xF5mUhN : {"errors":[

The installation name "MYPROJ" is the name of an old configuration that no longer exists and it is not referenced anymore by any Jenkins project, which is why I don't understand why it seems still to be used by sonar-scanner.
I tried cleaning the folder /var/lib/jenkins/.sonar/cache and upgrading the sonar-scanner-cli to version 4.8.1.3023 but I still encounter these errors.
Can you help me understand why this former installation name and these (old, I guess) analysis are fetched? What can I do to avoid such errors from happening?
 
Best regards
