Azure Pipeline - 如何使delayForMinutes任务使用变量中的值而不是硬编码值

Question

如何使延迟任务从变量中获取值而不是延迟ForMinutes输入的硬编码值？
当我执行以下操作时，它工作正常:

- job: WaitForDeploy
    dependsOn: Main
    pool: Server
    steps:
    - task: Delay@1
      inputs:
        delayForMinutes: '1'

但是当我这样做时它不会:

- job: WaitForDeploy
    dependsOn: Main
    pool: Server
    steps:
    - task: Delay@1
      inputs:
        delayForMinutes: '$(SleepCount)'

$(SleepCount) 在变量中定义为空字符串，然后通过以下方式从 python 脚本传递到管道:print(f'##vso[task.setvariable 变量=SleepCount]{delay_seconds}')我在之前的作业中打印出来，它正确显示了 intiger:

- script: 'echo $(SleepCount)'
      displayName: "print_sleep_count"

看起来这个变量值没有传递到我从 python 脚本返回它的作业之外，如何传递它？
这不起作用:

variables:
  SleepCount: ""

jobs:
  - job: Main
    pool:
      name: 'CDaaSLinux'

    [...]

    - task: PythonScript@0
      inputs:
        scriptSource: 'filePath'
        scriptPath: '$(Build.SourcesDirectory)/sleep_count.py'
      env:
        ACTUAL_START_DATE: $(ActualStartDate_value)

    - script: 'echo $(SleepCount)'
      name: setVariable
      displayName: "print_sleep_count"

    - script: 'echo "Waiting for Deploy for $(SleepCount) minutes"'
      displayName: "Deploy_message_for_user"
      
  - job: WaitForDeploy
    dependsOn: Main
    variables:
      SleepCount: $[ dependencies.Main.outputs['setVariable.SleepCount']]
    pool: Server
    steps:
    - task: Delay@1
      inputs:
        delayForMinutes: '$(SleepCount)'

为了在不同的阶段/作业中使用变量，您需要在设置变量时设置 isoutput 标志

print(f'##vso[task.setvariable variable=SleepCount;isoutput=true]{delay_seconds}')

Set an output variable for use in future jobs
