Jenkins并行声明式流水线

Question

我试图在声明式Jenkins流水线中定义一个并行段落。

我基于这个语法：https://jenkins.io/blog/2017/09/25/declarative-1/ 但我得到了这个错误：

WorkflowScript: 74: Expected one of "steps", "stages", or "parallel" for stage "app cores" @ line 74, column 3.
     stage('bat cores') {
     ^

我尝试过移动并行块，但是这样会导致其他错误。就我所知，我的代码与上面的博客帖子相匹配。

有什么建议吗？

版本：

• Jenkins 版本 2.138.1
• Pipeline: Declarative 版本 1.3.2

我的完整管道如下所示：

pipeline {
  agent { label 'master' }
  options {
    ansiColor('xterm')
  }
  parameters {
    choice(name: 'STOP_ON_FIRST_FAILURE', choices: ['true', 'false'], description: '....')
    choice(name: 'RUN_MODE', choices: [
      'plan, confirm, apply',
      'plan, confirm, apply, then destroy',
      'destroy'],
      description: "Choose to destroy resources at end" )
    string(name: 'GIT_REPO_BRANCH', defaultValue: 'production', description: '...')
  }
  stages {
    stage('thing container') {
      steps {
        build job: '/DevWork/DT/production branch/FA1/FA1 thing Creation', propagate: params.STOP_ON_FIRST_FAILURE
      }
    }

    stage('bat cores') {

错误信息不准确还是代码不准确？在那段代码中，stage('bat cores') 明显不在第74行。 - Matt Schuchard

Answer 1

你犯了一个错误，使用了开发博客中“负面”的例子：

在早期版本的Declarative Pipeline中，要想并行运行Pipeline代码块的唯一方式是在阶段的steps块内部使用parallel步骤，就像这样：YOUR EXAMPLE。虽然这种方法可以运行，但它与其他Declarative Pipeline语法不很好地集成。

我认为你的问题就在这里。

stage('app cores') {
      steps { // This step{} is causing the issue, remove it

在开发博客中，“真正的”语法标记如下：

但是现在，通过Declarative Pipeline 1.2版本，我们引入了一个真正的Declarative语法，用于并行运行阶段：

这将如下所示（只需从上面删除steps{}）：

stage('app cores') 
{
    parallel {
      stage('FA10302 Application Core') {
        steps {

          build(
            job: '/DevWork/DT/production branch/FA1/FA103/FA10302 Application Core',
            propagate: params.STOP_ON_FIRST_FAILURE,
            parameters: [
              [$class: 'StringParameterValue', name: 'RUN_MODE', value: params.RUN_MODE],
              [$class: 'StringParameterValue', name: 'GIT_REPO_BRANCH', value: params.GIT_REPO_BRANCH],
            ]
          )

        }
      }

      stage('FA10301 Application Core') {
        steps {

          build(
            job: '/DevWork/DT/production branch/FA1/FA103/FA10301 Application Core',
            propagate: params.STOP_ON_FIRST_FAILURE,
            parameters: [
              [$class: 'StringParameterValue', name: 'RUN_MODE', value: params.RUN_MODE],
              [$class: 'StringParameterValue', name: 'GIT_REPO_BRANCH', value: params.GIT_REPO_BRANCH],
            ]
          )

        }
      }

      stage('FA10101 Application Core') {
        steps {

          build(
            job: '/DevWork/DT/production branch/FA1/FA101/FA10101 Application Core',
            propagate: params.STOP_ON_FIRST_FAILURE,
            parameters: [
              [$class: 'StringParameterValue', name: 'RUN_MODE', value: params.RUN_MODE],
              [$class: 'StringParameterValue', name: 'GIT_REPO_BRANCH', value: params.GIT_REPO_BRANCH],
            ]
          )
        }
      }
    } // close the stage 'app cores'

谢谢，是的，就是这样。我不应该在parallel()之前加上steps()。 - David Roussel

Answer 2

这听起来可能很蠢，但是我今天发现， parallel 单词中的拼写错误也会导致这个异常。
