如何锁定声明性詹金斯管道的多个阶段？

jenkins

我想在声明性Jenkins管道内的锁内运行多个阶段：

pipeline {
    agent any
    stages {
        lock(resource: 'myResource') {
            stage('Stage 1') {
                steps {
                  echo "my first step"
                }
            }

            stage('Stage 2') {
                steps {
                  echo "my second step"
                }
            }

        }
    }
}

我收到以下错误：

Started by user anonymous
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 10: Expected a stage @ line 10, column 9.
           lock(resource: 'myResource') {
           ^

WorkflowScript: 10: Stage does not have a name @ line 10, column 9.
           lock(resource: 'myResource') {
           ^

WorkflowScript: 10: Nothing to execute within stage "null" @ line 10, column 9.
           lock(resource: 'myResource') {
           ^

3 errors

这是什么问题该文档明确指出：

lock 也可以用于将多个阶段包装到单个并发单元中

问题是，尽管事实上在2016年9月Beta版中提供了声明式管道，但您引用的博客文章（自10月起）记录的是脚本化管道，而不是声明式的（声明不多，所以我觉得您痛）。尚未将可锁定资源作为声明性管道步骤来使用，而该方式不能启用您正在寻找的功能。

你可以做：

pipeline {
  agent { label 'docker' }
  stages {
    stage('one') {
      steps {
        lock('something') {
          echo 'stage one'
        }
      }
    }
  }
}

但是你不能做：

pipeline {
  agent { label 'docker' }
  stages {
    lock('something') {
      stage('one') {
        steps {
          echo 'stage one'
        }
      }
      stage('two') {
        steps {
          echo 'stage two'
        }
      }
    }
  }
}

而且你不能做：

pipeline {
  agent { label 'docker' }
  stages {
    stage('one') {
      lock('something') {
        steps {
          echo 'stage one'
        }
      }
    }
  }
}

您可以在此用例中使用脚本化管道。
