azure-devops - 根据提交消息跳过阶段

Question

我正在尝试将 Azure DevOps 设置为跳过 multi-stage pipeline 上的一个阶段如果消息不以给定文本开头。

来自 examples documentation ，我认为这只是

  - stage: t1
    condition: not(startsWith(variables['Build.SourceVersionMessage'], '[maven-release-plugin]'))
    jobs:
      - job: ReleasePrepare
        displayName: Prepare release
        pool:
          vmImage: 'ubuntu-16.04'
        steps:
          - script: |
              env | sort

但是，无论如何都会执行。这是我期望 t1 的示例不基于提交消息运行的任务 https://dev.azure.com/trajano/experiments/_build/results?buildId=110&view=results
env的输出显示消息被正确传递



以防万一这是一个错误，我也在这里报告了 https://developercommunity.visualstudio.com/content/problem/697290/startswith-buildsourceversionmessage-variable-not.html

看来Build.SourceVersionMessage在这篇文章发表时只能在 steps 上解析.

这是一个工作示例，它在一个步骤中将值存储在变量中并在下一个作业中使用它(可以是 deployment )

trigger:
  batch: true
  branches:
    include:
      - master

stages:
  - stage: ci
    displayName: Continuous Integration
    jobs:
      - job: Build
        pool:
          vmImage: 'ubuntu-16.04'
        steps:
          - script: |
              env | sort
              echo "$(Build.SourceVersionMessage)"
  - stage: t1
    displayName: Release
    condition: eq(variables['Build.SourceBranch'],'refs/heads/master')
    jobs:
      - job: GetCommitMessage
        displayName: Get commit message
        steps:
          - bash: |
              echo "##vso[task.setvariable variable=commitMessage;isOutput=true]$(Build.SourceVersionMessage)"
              echo "Message is '$(Build.SourceVersionMessage)''"
            name: SetVarStep
            displayName: Store commit message in variable
      - job: ReleasePrepare
        displayName: Prepare release
        dependsOn: GetCommitMessage
        pool:
          vmImage: 'ubuntu-16.04'
        condition: not(startsWith(dependencies.GetCommitMessage.outputs['SetVarStep.commitMessage'], '[maven-release-plugin]'))
        steps:
          - script: |
              echo this would be a candidate for release
              env | sort
            displayName: Don't do it if maven release
      - job: NotReleasePrepare
        displayName: Don't Prepare Release
        dependsOn: GetCommitMessage
        pool:
          vmImage: 'ubuntu-16.04'
        condition: startsWith(dependencies.GetCommitMessage.outputs['SetVarStep.commitMessage'], '[maven-release-plugin]')
        steps:
          - script: |
              echo this not be a candidate for release because it was created by the plugin
              env | sort
            condition: startsWith(variables.commitMessage, '[maven-release-plugin]')
            displayName: Do it if maven release
