如何使用从一个阶段到下一个阶段的输出的环境变量？

Question

如何将我的环境变量从第一阶段转移到第二阶段？

发出->我从回显结果中得到一个空的"“值。

azure-pipeline.yml

trigger:
  branches:
    include:
    - main
  paths:
    include:
    - infra/*
    - .pipelines/*

variables:
  vmImageName: 'ubuntu-latest'
  root: $(System.DefaultWorkingDirectory)

stages:
- stage: TakePITR
  dependsOn: []
  variables:
    env: poc
  jobs:
  - job: GetPitrTime
    steps:
    - task: PowerShell@2
      inputs:
        targetType: 'inline'
        script: |
          $iso8601_time = Get-Date -Format "o"
          echo "##vso[task.setvariable variable=pitr_time;isOutput=True]$iso8601_time"
        name: PitrVar
        displayName: "Get point-in-time before second stage"

- stage: TestOutputEnvVar
  dependsOn: TakePITR
  variables:
    env: poc
    PITR: $[ stageDependencies.TakePITR.GetPitrTime.outputs['PitrVar.pitr_time']]
  jobs:
  - job:
    steps:
    - script: |
        echo $pitr_time
        echo $PITR
      displayName: 'echo value'

我不明白我到底做错了什么。

这是我的流水线的结果：

您有合同问题：

    - task: PowerShell@2
      inputs:
        targetType: 'inline'
        script: |
          $iso8601_time = Get-Date -Format "o"
          echo "##vso[task.setvariable variable=pitr_time;isOutput=true]$iso8601_time"
      name: PitrVar
      displayName: "Get point-in-time before second stage"

名称和displayName应与输入位于同一级别，然后：
