    Description

      Here is my pipeline code:

          Map scm = [
        $class: 'GitSCM',
        extensions: [
            [$class: 'RelativeTargetDirectory', relativeTargetDir: conf.dir],
            [$class: 'CleanCheckout'],
            [$class: 'PruneStaleBranch']
        ],
        browser: [
            $class: 'GitLab',
            repoUrl: "https://hide/${conf.name}", version: '8.16'
        ],
        userRemoteConfigs: [[
            credentialsId: 'Gitlab-CI-SSH-KEY',
            refspec: '+refs/merge-requests/*/head' +
                     ':refs/remotes/origin/merge-requests/*',
            url: "git@hide:${conf.name}.git"
        ]]
    ]

    switch(env.gitlabActionType) {
        case 'PUSH':
            scm.branches = [[name: "${env.gitlabSourceBranch}"]]
            break
        case 'MERGE':
            scm.branches = [[name: "merge-requests/${env.gitlabMergeRequestIid}/head"]]
            break
        default:
            scm.branches = [[name: conf.refs ?: 'master' ]]
    }

    echo "Using this scm branches config: ${scm.branches}"
    checkout scm

      But I find the exist branches not update. Here is the console output:

      Using this scm branches config: [[name:dev]]

 > git rev-parse --verify HEAD # timeout=10

 > git reset --hard # timeout=10
 > git clean -fdx # timeout=10

      Jenkins think origin/dev sha-1 is 1065454f788597d370a34de5f05570cc9074b618, but in fact it's 26d6a19. I try to access to jenkins workspace and exec git fetch, the branches updated:

      $ git fetch 
remote: Counting objects: 4, done.
remote: Compressing objects: 100% (4/4), done.
remote: Total 4 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (4/4), done.
From hide:devops/Jenkinsfiles
   1065454..26d6a19  dev        -> origin/dev
   f6b526b..e70443c  master     -> origin/master

      So git plugin does not update the exist branches, because git fetch --tags does not fetch the exist branches, see: http://stackoverflow.com/questions/1204190/does-git-fetch-tags-include-git-fetch

      EDIT:
      It's my fault, because I set the wrong refspec. I've edited my title. According to gitlab docs, to get merge request must set another git refspec: https://docs.gitlab.com/ee/user/project/merge_requests/index.html#checkout-locally-by-modifying-git-config-for-a-given-repository

      How to do this?
