尽管值为真，但阶段条件未评估为真

Question

我有一个阶段要运行。条件是true，但阶段一直被跳过，我不确定为什么。

这是舞台：

stages:
- stage: UnitTests
  displayName: Run unit tests on service...
  condition: eq(stageDependencies.Changed.Changes.outputs['detectChange.anyServicesChanged'], true)
  dependsOn: Changed
  variables: 
    test: $[ stageDependencies.Changed.Changes.outputs['detectChange.anyServicesChanged'] ]
  jobs:
  - job: UnitTests
    displayName: Running unit tests...
    steps:
    - bash: |
        echo $(test)

或者将其赋值给一个变量：

stages:
- stage: UnitTests
  displayName: Run unit tests on service...
  variables: 
    test: $[ stageDependencies.Changed.Changes.outputs['detectChange.anyServicesChanged'] ]
  condition: eq(variables.test, true)
  # dependsOn: Changed
  jobs:
  - job: UnitTests
    displayName: Running unit tests...
    steps:
    - bash: |
        echo $(test)

但是，如果我注释掉 condition 和 dependsOn，果然 echo $(test) 会打印出 true。

stages:
- stage: UnitTests
  displayName: Run unit tests on service...
  # condition: eq(stageDependencies.Changed.Changes.outputs['detectChange.anyServicesChanged'], true)
  # dependsOn: Changed
  variables: 
    test: $[ stageDependencies.Changed.Changes.outputs['detectChange.anyServicesChanged'] ]
  jobs:
  - job: UnitTests
    displayName: Running unit tests...
    steps:
    - bash: |
        echo $(test)

这是检测到变化的阶段：

stages:
- stage: Changed
  displayName: Checks for changes in services and configs...
  jobs:
  - job: Changes
    displayName: Checking for changes in services and configs...
    steps:
    - bash: |
        mapfile -t servicesChanged < <(git diff  HEAD origin/production --name-only | awk -F'/' 'NF!=1{print }' | sort -u)
        echo "Total Changed: ${#servicesChanged[@]}"
        if [[ ${#servicesChanged[@]} > 0 ]]; then
          echo "Any services changed: True"
          echo "##vso[task.setvariable variable=anyServicesChanged;isOutput=true]true"
        fi
      name: detectChange

所以我不确定我在这里做错了什么，当 condition 和 dependsOn 处于活动状态时，它一直跳过这个阶段。有什么建议吗？

Answer 1

当你在一个阶段使用这个条件（Stage depending on job output）时，你必须使用dependencies变量，而不是stageDependencies。因此以下语法应该有效。

- stage: UnitTests
  displayName: Run unit tests on service...
  condition: eq(dependencies.Changed.outputs['Changes.detectChange.anyServicesChanged'], true)
  dependsOn: Changed

有关详细信息，请参阅：Stage depending on job output。

尽管值为真，但阶段条件未评估为真

Stage condition is not evaluating to true despite the value being true
