Azure DevOps Pipeline跨Job传递变量失败求助

问题背景 #

尝试配置Azure DevOps Pipeline实现Job间变量传递，参考官方文档编写YAML后，同一Job内引用变量正常，但跨Job访问目标变量时输出空值。

配置代码 #

pool:
  name: ubuntu

parameters:
- name: sourceArtifactPath
  type: string

jobs:
- job: Setup
  steps:
  - script: echo "##vso[task.setvariable variable=Name;isOutput=true]$(basename ${{ parameters.sourceArtifactPath }})"
    name: SetVariables
    displayName: "Set Pipeline Variables"
  - script: echo $(SetVariables.Name)

- job: DoStuff
  dependsOn: Setup
  steps:
  - bash: echo "Important work has been done"

- job: Upload
  dependsOn: DoStuff
  variables:
    artifactName: $[ dependencies.Setup.outputs['SetVariables.Name'] ]
  steps:
  - script: echo $(artifactName)
    displayName: "Print Filename"

错误现象 #

Upload Job中尝试访问Setup.SetVariables.Name时输出空值，控制台输出：

==============================================================================
Generating script.
Script contents:
echo 
========================== Starting Command Output ===========================

问题原因及解决方案 #

核心原因1：依赖关系缺失 #

Azure DevOps中，Job要读取另一个Job的输出变量，必须直接依赖该Job。当前Upload Job仅依赖DoStuff，未直接依赖Setup，因此无法获取Setup的输出变量。

解决方案1：添加直接依赖

修改Upload Job的dependsOn，同时包含Setup和DoStuff：

- job: Upload
  dependsOn: [Setup, DoStuff]
  variables:
    artifactName: $[ dependencies.Setup.outputs['SetVariables.Name'] ]
  steps:
  - script: echo $(artifactName)
    displayName: "Print Filename"

核心原因2：YAML格式问题（可选排查） #

检查YAML中的空格是否为半角空格，全角空格会导致变量解析失败。确保artifactName: 后面是半角空格，而非全角空格。

备选解决方案：通过中间Job传递变量 #

如果不想让Upload直接依赖Setup，可以在DoStuff Job中将Setup的变量重新输出为自身的输出变量：

- job: DoStuff
  dependsOn: Setup
  variables:
    setupName: $[ dependencies.Setup.outputs['SetVariables.Name'] ]
  steps:
  - bash: echo "Important work has been done"
  - script: echo "##vso[task.setvariable variable=Name;isOutput=true]$(setupName)"
    name: PassVariables

- job: Upload
  dependsOn: DoStuff
  variables:
    artifactName: $[ dependencies.DoStuff.outputs['PassVariables.Name'] ]
  steps:
  - script: echo $(artifactName)
    displayName: "Print Filename"
