azure-pipelines - 从部署作业中检索输出变量

Question

在下面的示例中，我能够访问 jobA 的输出变量，但不能访问 deploymentA 的输出变量。主要区别在于 jobA 是“正常”作业，而 deploymentA 是部署作业。

jobs:
- deployment: deploymentA
  environment: Test
  strategy:
    runOnce:
      deploy:
        steps:
        - checkout: none
        - pwsh: |
            echo "##vso[task.setvariable variable=someVar;isOutput=true]someValue"
          name: someName

- job: jobA
  steps:
  - checkout: none
  - pwsh: |
      echo "##vso[task.setvariable variable=someVarA;isOutput=true]someValueA"
    name: someNameA

- job: jobB
  dependsOn: 
  - deploymentA
  - jobA

  variables:
    deployJobVar: $[dependencies.deploymentA.outputs['someName.someVar']]
    jobVar: $[dependencies.jobA.outputs['someNameA.someVarA']]

  steps:
  - checkout: none
  - pwsh: |
      echo "$(deployJobVar)"    # will display empty string
      echo "$(jobVar)"          # will display 'someValueA'

best hint我发现是:

If you're setting a variable from a matrix or slice, then to reference the variable, you have to include the name of the job as well as the step when you access it from a downstream job.

不完全相同，但我尝试在前面添加类似的标识符，但以下方法均无效:

$[dependencies.deploymentA.outputs['runOnce.someName.someVar']]
$[dependencies.deploymentA.outputs['deploy.someName.someVar']]
$[dependencies.deploymentA.outputs['runOnce.deploy.someName.someVar']]

有人知道访问部署作业输出的特定变量的正确语法吗？或者，有人知道如何显示所有输出的变量吗？

Answer 1

目前文档还不完整，但是只要发挥一点想象力，我们可以注意到 Set a multi-job output variable 的第二部分适用。

您需要做的就是使用作业名称作为前缀来引用变量:deploymentA.someName.someVar 而不是 someName.someVar:

deployJobVar: $[dependencies.deploymentA.outputs['deploymentA.someName.someVar']]

是的，deploymentA 出现了两次。
