Azure devops 管道、powershell 拆分字符串、转换为 json 并分配给管道变量不起作用

Question

我想将管道变量（分隔字符串）转换为 json 数组并将 json 数组分配给另一个管道变量。请参阅下面的代码，输出保持为空。我在这里错过了什么？

脚本：

steps:
  - task: PowerShell@2
    inputs:
      targetType: inline
      script: |
        $test = "LZ-UK;LZ-ES;LZ-NL"
        $json = $test.Split(";") | ConvertTo-Json -AsArray
        Write-Host "##vso[task.setvariable variable=JsonLZ]$json"
        Write-Host "Assigned the variable"
        Write-Host "New `r`n $($JsonLZ)"
  - script: |
       echo ${{ variables.JsonLZ }}

输出：

你非常接近。我发现您的 YAML/PowerShell:

存在一些小问题

你忘了"##vso[task.setvariable variable=JsonLZ]$json"中变量名后面的分号，应该是："##vso[task.setvariable variable=JsonLZ;]$json"
您应该使用 $(JsonLZ) 而不是 ${{ variables.JsonLZ }}。前者将在 runtime 时评估，后者在 compile-time 时评估。这是 MS 文档的 link：Understand variable syntax

试一试以查看工作示例：

name: Whosebug-Example-Pipeline
trigger:
    - none
variables:
  JsonLZ: 'UNSET'
stages:
    - stage: StageA
      displayName: "Stage A"
      jobs:
        - job: example_job
          displayName: "Example Job"
          pool:
            vmImage: "ubuntu-latest"
          steps:
          - task: PowerShell@2
            inputs:
              targetType: inline
              script: |
                  $test = "LZ-UK;LZ-ES;LZ-NL"
                  $json = $test.Split(";") | ConvertTo-Json -Compress
                  Write-Host "##vso[task.setvariable variable=JsonLZ;]$json"
                  Write-Host "Assigned the variable"
          - script: |
              echo $(JsonLZ)
              echo ${{ variables.JsonLZ }}

Azure devops 管道、powershell 拆分字符串、转换为 json 并分配给管道变量不起作用

Azure devops pipeline, powershell split string, convert to json and assign to pipeline variable doesn't work

powershell

json
