Jenkins-Pipeline内部特定阶段的Checkout子模块

Question

给出带有特定管道的Jenkinsfile。我想通过不立即拉出子模块来节省特定运行器上的空间。因此，我尝试在结帐阶段拉出子模块：

...
        stage('checkout') {
        steps {
            checkout([ 
                $class: 'GitSCM',
                branches: [[name: '**']],
                doGenerateSubmoduleConfigurations: false, 
                extensions: 
                    [[$class: 'SubmoduleOption',
                    disableSubmodules: false,
                    parentCredentials: false,
                    recursiveSubmodules: true,
                    reference: '',
                    trackingSubmodules: false
                    ]],
                submoduleCfg: [],
                userRemoteConfigs:
                    [[credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
                    url: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx']]
            ])
        }
    }
...

给定阶段的输出是

...
[Pipeline] {
[Pipeline] stage
[Pipeline] { (checkout)
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Build)
Stage "Build" skipped due to earlier failure(s)
...

为什么我至少没有收到错误消息？
