Hi All,

I'm getting this following error which is happening for a particular gerrit 
repo. The configuration is working for all other repos in my project but 
not in this particular one.

Sounds more like a problem on the gerrit side. Maybe 
check 
https://confluence.atlassian.com/fishkb/git-indexing-fails-due-to-bad-pack-header-371360062.html
 
for one reason.
 

The multibranch pipeline catalog template is
multibranch:
  branchSource:
    gerrit:
      remote: ${ProjectRepositoryUrl}
      credentialsId: ${GitHTTPSCredentials}
      traits:
        - $class: ChangeDiscoveryTrait
          queryString: ''
        - $class: RefSpecsSCMSourceTrait
          templates:
          - value: '+refs/heads/*:refs/remotes/@{remote}/*'
        - $class: SubmoduleOptionTrait
          extension:
            disableSubmodules: false
            recursiveSubmodules: true
            parentCredentials: true  

and pipeline config is 
pipeline {
    /**###################### Agents Config ######################**/
    agent {
        kubernetes {
            inheritFrom "${PodName}"
        }
    }
    options {
        // This will checkout the changed repository that has triggered 
this pipeline to a sperate folder named "tmp_repository", to be used later 
in the build
        checkoutToSubdirectory('tmp_repository')
        buildDiscarder(logRotator(numToKeepStr: 'unlimited'))
    }

    /**###################### Stages ######################**/
    stages {
        /**###################### Gerrit Review Log 
######################**/
        stage('Init') {
            steps {
                script {
                    gerritReview message: "Build started: ${BUILD_URL}"
                }
            }
        }
        /**###################### Cloning Manifest Repository 
######################**/
        stage('Cloning Manifest Repo') {
            steps { // Executes on JNLP, no specific container required
                script {
                    echo "Cloning the Manifest repository: ${
ManifestRepoName}"
                    // This will checkout the manifest repository into a 
folder under the same name as the repository
                    dir("${ManifestRepoName}") {
                        checkout([
                        $class: 'GitSCM',
                        branches:
                        [[name: "*/${ManifestBranch}"]],
                        doGenerateSubmoduleConfigurations: false,
                        extensions: [[
                            $class: 'LocalBranch',
                            localBranch: '**'
                          ],[
                            $class: 'CleanBeforeCheckout',
                            deleteUntrackedNestedRepositories: false
                          ]],
                        submoduleCfg: [],
                        userRemoteConfigs: [[credentialsId: 
GitHTTPSCredentials, /*Netid credentials must be used instead of HTTPS 
tokens.*/
                                             url: ManifestRepoUrl]]
                        ])
                    }
                }
            }
        }
}


The multibranch indexing itself is not happening and it is unable to detect 
Gerrit branches/changes

Can someone assist on this
