    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?

          Please ask questions about usage on the jenkins users mailing list.

          Asking a question in a bug report requires time from the very few people who read bug reports on the git plugin, while questions on the jenkins users mailing list spreads the time across many more people.

          Since the online help doesn't describe how to do that, I've added online help which describes how to do it.
