如何在 Github Action 中让有条件的工作需要另一份工作

Question

以下是我的 GitHub 工作流程

name: APP Build
on:
  push:
    branches:
      - feature/test

jobs:
  test-1:
    runs-on: ubuntu-latest
    if: ${{ github.event_name == 'push' && contains( github.event.head_commit.message, 'test1') }}
    steps:
      - name: test-fail
        run: echo "test1"
  test-2:
    runs-on: ubuntu-latest
    if: ${{ github.event_name == 'push' && contains( github.event.head_commit.message, 'test2') }}
    steps:
      - name: test-fail
        run: echo "test1"
  notify-slack:
    name: Slack Notification
    runs-on: ubuntu-latest
    needs: [test-1, test-2]
    steps:
      - name: Slack Notification
        uses: rtCamp/action-slack-notify@v2.2.0
        env:
          SLACK_CHANNEL: alert
          SLACK_COLOR: "${{ job.status == 'success' && 'good' || 'danger' }}"

问题：test1 和 test2 根据我的提交消息，作业是有条件的，但通知 slack 需要 test1 或 test2。我不能同时放两者，因为如果其中一个作业跳过notify-slack 也会跳过。如何使这项工作？

Github about this 存在问题。您需要添加如下条件：

  test-1:
    runs-on: ubuntu-latest
    if: ${{ github.event_name == 'push' && contains( github.event.head_commit.message, 'test1') }}
    steps:
      - name: test-fail
        run: echo "test1"
  test-2:
    runs-on: ubuntu-latest
    if: ${{ github.event_name == 'push' && contains( github.event.head_commit.message, 'test2') }}
    steps:
      - name: test-fail
        run: echo "test1"
  notify-slack:
    name: Slack Notification
    runs-on: ubuntu-latest
    needs: [test-1, test-2]
    if: |
      always() && 
      (needs.test-1.result == 'success' || needs.test-1.result == 'skipped') && 
      (needs.test-2.result == 'success' || needs.test-2.result == 'skipped') && 
      !(needs.test-1.result == 'skipped' && needs.test-2.result == 'skipped')
    steps:
      - name: Slack Notification
        uses: rtCamp/action-slack-notify@v2.2.0
        env:
          SLACK_CHANNEL: alert
          SLACK_COLOR: "${{ job.status == 'success' && 'good' || 'danger' }}"

可以使用以下工作流逻辑来实现这样的条件

jobs:
  A:
    runs-on: ubuntu-latest
    steps:
      - run: echo "success always"
  B:
    runs-on: ubuntu-latest
    if: false
    steps:
      - run: echo "this will never run"
  C:
    runs-on: ubuntu-latest
    steps:
      - run: |
          exho "here to fail"
          exit 1

  D:
    runs-on: ubuntu-latest
    needs: [A, B, C]
    if: |
      always() &&
      !contains(needs.*.result, 'cancelled')
    # you can add conditions if needed e.g.
    # !contains(needs.*.result, 'failure')
    steps:
      - run: echo "${{ toJSON(needs) }}"

您还需要修改 SLACK_COLOR 逻辑。 job.status == 'success' 将不起作用，因为无论任何依赖项是否失败，对于此作业，它将始终为 success。将needs 用于您的逻辑，例如工作D 输出是：

{
  A: {
    result: success,
    outputs: {}
  },
  B: {
    result: skipped,
    outputs: {}
  },
  C: {
    result: failure,
    outputs: {}
  }
}

所以你SLACK_COLOR 可以这样设置

SLACK_COLOR: "${{ contains(needs.*.result, 'failure') && 'danger' || 'good' }}"
