Azure Pipeline：如何通知用户阶段因条件未满足而跳过？

• 给阶段加前置检查步骤，强制输出原因
  在目标阶段里新增一个condition: always()的前置Job，不管主Job是否执行，这个检查Job都会运行，直接在日志里输出条件判断结果。示例配置：

  stages:
  - stage: Test
    condition: eq(variables['Build.SourceBranch'], 'refs/heads/main')
    jobs:
    - job: CheckCondition
      condition: always()
      steps:
      - script: |
          if [ "$BUILD_SOURCEBRANCH" = "refs/heads/main" ]; then
            echo "✅ 满足条件：当前分支为main，将执行Test阶段"
          else
            echo "❌ 未满足条件：当前分支是$BUILD_SOURCEBRANCH，仅main分支触发Test阶段"
          fi
        displayName: '检查Test阶段执行条件'
    - job: ActualTest
      dependsOn: CheckCondition
      condition: eq(variables['Build.SourceBranch'], 'refs/heads/main')
      steps:
      - script: echo "执行测试任务..."
  

• 把原因嵌入阶段名称，直观展示
  先在前置阶段计算条件结果和原因，通过输出变量传递给目标阶段，直接把原因写到阶段的displayName里，用户在流水线概览页就能看到。示例配置：

  variables:
    - name: TestStageReason
      value: ''
  stages:
  - stage: PreCheck
    jobs:
    - job: EvaluateConditions
      steps:
      - script: |
          if [ "$BUILD_SOURCEBRANCH" = "refs/heads/main" ]; then
            echo "##vso[task.setvariable variable=TestStageReason;isOutput=true]✅ 满足条件：当前分支为main"
            echo "##vso[task.setvariable variable=ShouldRunTest;isOutput=true]true"
          else
            echo "##vso[task.setvariable variable=TestStageReason;isOutput=true]❌ 未满足条件：仅main分支允许执行Test阶段，当前分支为$BUILD_SOURCEBRANCH"
            echo "##vso[task.setvariable variable=ShouldRunTest;isOutput=true]false"
          fi
        name: ConditionEval
  - stage: Test
    condition: eq(dependencies.PreCheck.outputs['ConditionEval.ShouldRunTest'], 'true')
    displayName: "Test $(dependencies.PreCheck.outputs['ConditionEval.TestStageReason'])"
    jobs:
    - job: RunTests
      steps:
      - script: echo "执行测试..."
  

• 用日志命令添加醒目警告
  专门加一个仅在条件不满足时运行的Job，用Azure Pipeline的日志命令输出警告信息，这个警告会显示在流水线摘要页，不用点进日志就能看到。示例配置：

  stages:
  - stage: Test
    jobs:
    - job: TestJob
      condition: eq(variables['Build.SourceBranch'], 'refs/heads/main')
      steps:
      - script: echo "执行测试任务..."
    - job: SkipReason
      condition: ne(variables['Build.SourceBranch'], 'refs/heads/main')
      steps:
      - script: |
          echo "##vso[task.logissue type=warning]Test阶段已跳过：当前分支为$BUILD_SOURCEBRANCH，仅main分支触发执行"
        displayName: '输出Test阶段跳过原因'
