我的环境是下一个：

• Jenkins2.46.1
  -Gitlab插件1.4.5
  -GitLab社区版8.14.3
  我已配置多分支管道。我已尝试：

pipeline {
    agent any
    options {
      gitLabConnection('MY_GITLAB')
      gitlabCommitStatus(name: 'jenkins')
    }
    triggers {
        gitlab(triggerOnPush: true, triggerOnMergeRequest: true, branchFilterType: 'All')
    }
    stages {

        stage("build") {
            steps {
                gitlabCommitStatus(name: 'build') {
                withMaven(
                            maven: 'maven3', // Maven installation declared in the Jenkins "Global Tool Configuration"
                            mavenSettingsConfig: 'MY_ID', // Maven settings.xml file defined with the Jenkins Config File Provider Plugin
                            mavenLocalRepo: '.repository') {
                                // Run the maven build
                                sh "mvn clean install"
                            }
                }               
            }
        }

        stage("paralelo") {
        steps {
            parallel (
                    phase1: { sh "echo phase1" },
                    phase2: { sh "echo phase2" }
                    )
                }
        }
    }
}

它可以在没有错误的情况下工作，但是我在我的Gitlab中看不到提交状态。
感谢所有人！
