Azure DevOps Pipelines跨Job传递变量失败问题求助

我在Azure DevOps Pipelines的SmokeTests阶段内，尝试从E2ETests Job向SendNotificationPass Job传递reportUrl变量，用于通过Bash脚本发送Teams消息（Webhook功能正常）。

E2ETests Job里通过AWSShellScript任务设置了output类型的reportUrl变量，该步骤能正常生成并输出报告URL，但在SendNotificationPass Job中引用时出现语法错误：

/home/vsts/work/_temp/xxx.sh: line 2: stageDependencies.SmokeTests.E2ETests.outputs['upload_allure_report8.reportUrl'] : syntax error: invalid arithmetic operator (error token is ".SmokeTests.E2ETests.outputs['upload_allure_report8.reportUrl'] ")

已尝试用dependencies替代stageDependencies、省略阶段名称等方法，问题仍未解决。相关流水线代码如下：

stages:
  - stage: SmokeTests
    displayName: Smoke Tests
    jobs:

      - job: E2ETests
        displayName: E2E Tests
        condition: and(succeeded(), not(contains(variables['Build.SourceVersionMessage'], 'skip ci')))
        pool: xxx-$(ENV_NAME)-e2e
        steps:
      - checkout: self
      - checkout: E2ETests

          - task: AWSShellScript@1
            displayName: Upload Allure report
            name: upload_allure_report8
            condition: always()
            inputs:
              awsCredentials: $(IT_CONNECTION_NAME)
              regionName: $(REGION)
              scriptType: "inline"
              #this works fine, I can see the URL
              inlineScript: |
                set -e
                export REPORT_URL=https://${ALLURE_S3_BUCKET}/${{parameters.ALLURE_REPORT_ENV}}/$(Build.BuildNumber)/index.html
                echo Report URL: ${REPORT_URL}
                echo "##vso[task.setvariable variable=reportUrl;isOutput=true;]${REPORT_URL}"

      - job: SendNotificationPass
        displayName: 'Send Teams Notification - Succeeded'
        dependsOn: E2ETests
        condition: eq(dependencies.E2ETests.result, 'succeeded')
        variables:
          reportUrl: $[ stageDependencies.SmokeTests.E2ETests.outputs['upload_allure_report8.reportUrl'] ]
        steps: |
          echo "E2E test status: PASSED. The report URL is ${{ variables.reportUrl }}}"
          MESSAGE="{"text": "E2E test status: PASSED. The report URL is: ${{ variables.reportUrl }}"}"
          curl -X POST -H "Content-Type: application/json" -d "$MESSAGE" $(WEBHOOK)

问题根源 #

1. 变量引用语法混淆：在Bash脚本中使用了${{ variables.reportUrl }}（编译时替换），但跨Job输出变量需要运行时替换，编译时替换会直接把表达式字符串写入脚本，导致Bash解析错误。
2. 阶段内跨Job变量引用错误：同一阶段内的Job依赖，应该用dependencies而非stageDependencies（stageDependencies用于跨阶段引用）。

修正后的代码 #

将SendNotificationPass Job部分修改为：

- job: SendNotificationPass
  displayName: 'Send Teams Notification - Succeeded'
  dependsOn: E2ETests
  condition: eq(dependencies.E2ETests.result, 'succeeded')
  variables:
    # 同一阶段内用dependencies引用跨Job输出变量
    reportUrl: $[ dependencies.E2ETests.outputs['upload_allure_report8.reportUrl'] ]
  steps:
    - bash: |
        echo "E2E test status: PASSED. The report URL is $(reportUrl)"
        MESSAGE='{"text": "E2E test status: PASSED. The report URL is: $(reportUrl)"}'
        curl -X POST -H "Content-Type: application/json" -d "$MESSAGE" $(WEBHOOK)
      displayName: Send Teams Notification

关键修改点 #

• 变量引用方式：在Bash脚本中用$(reportUrl)（运行时变量替换）替代${{ variables.reportUrl }}，避免将表达式字符串直接传入Bash导致语法错误。
• 跨Job变量引用：同一阶段内的Job依赖，使用dependencies.JobName.outputs['StepName.VariableName']格式。
• JSON字符串转义：Bash中定义JSON字符串时用单引号包裹，避免双引号嵌套导致解析问题。
