Gitlab Merge Request Analysis has no code

[oers (Stefan Moritz Murawski)]

Must-share information (formatted with Markdown):

• Versions
  Sonar Dev Edition 8.5.1.38104
  ** Gitlab 13.5.3 (eaa194f15e6)
  ** Jenkins Jenkins 2.263.1
• I am evaluating the branch analysis functionality and what it to report new Bugs etc
• I Set-Up everything according to: https://docs.sonarqube.org/latest/analysis/jenkins/#header-3

Analysis is running for the branches/merge requests and the pull request decoration in gitlab works.

But the Page in sonar is empty and no code is shown:

Jenkins Settings:

PipelineScript:

        stage('git') {
           git credentialsId: '6d936a5f-ca5b-428a-a33a-44402899e4f9', url:       'git@gitlab.de.ebpgroup.corp:paussb/PAUSS-B.git'
          }
  
    lock(quantity: 1, resource: 'sonar-paussb') {
        stage('SonarQube Scan') {
              withSonarQubeEnv('Sonar-DevEdition') {
                  withMaven(jdk: 'amazon-coretto-jdk8-latest', maven: 'Apache Maven latest', options:       [artifactsPublisher(disabled: true)]) {
  
                    bat 'mvn -P coverage -Djavafx.verbose=true -Dprism.verbose=true       -Djavax.persistence.jdbc.server=paussb-jenkins-sonar -Dmaven.test.failure.ignore=true clean verify sonar:sonar'
                  } // SonarQube taskId is automatically attached to the pipeline context
              }
        }
    }
    cleanWs()

The Problem here was, that the git checkout always checked out the master

To checkout the pull request the following has to be done

checkout([$class: 'GitSCM', branches: [[name: '*/${CHANGE_BRANCH}']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CloneOption', noTags: false, reference: '', shallow: false]], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '6d936a5f', url: 'git@gitlab']]])

the branches has to bet set to:

  branches: [[name: '*/${CHANGE_BRANCH}']], 

BRANCH_NAME was not working in my case with gitlab, because this variable reported a non exitent branch. This Variable contains the NAME of the MR.

Glad you found what was the problem - thanks for posting.
