Jenkins 并行声明式管道

Question

我正在尝试在我的声明式 jenkins 管道中定义一个并行部分。

我的语法是这样的：https://jenkins.io/blog/2017/09/25/declarative-1/

但我收到此错误：

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

我尝试移动并行块，但随后出现其他错误。据我所见，我与上面的博文相符。

有什么想法吗？

版本：

• 詹金斯版本。 2.138.1
• 管道：声明性版本 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

Answer 1

你错误地使用了开发博客的“反面”例子：

在声明式管道的早期版本中，唯一的运行方式 并行管道代码块是使用并行步骤 在阶段的步骤块内，如下所示：您的示例

虽然这行得通，但它并不能很好地与 声明式管道语法。

我认为您的问题出在此处：

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

“真正的”语法在开发博客中标记如下：

但是现在在声明式管道 1.2 中，我们引入了一个真正的 并行运行阶段的声明语法：

如下所示（只需从上面删除您的步骤{}）：

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'

这听起来可能很愚蠢，但正如我今天发现的那样，parallel 一词中的拼写错误也会引发此异常。
