Github Action Trigger on multiple on: push: paths答案

【问题描述】：

在单个 repo 中，我想为不同的路径 [paths: 'frontend/**' 和 paths: 'backend/**'] 创建多个触发器，并为（相同的）构建作业使用不同的参数。以下是两个工作流程。

name: Trigger Jenkins Build [ Build-Portal ]
on:
  push:
    branches: [ develop ]
    paths: 'frontend/**'
    types: [closed]
jobs:
  build:
    name: Triggering Jenkins Build [ Build-Portal ]
    runs-on: ubuntu-latest
    if: github.event.pull_request.merged == true
    steps:
    - name: Trigger Build-Portal
      uses: actions/trigger-jenkins@develop
      with:
        ...
        job_name: "Build-Portal"
        job_params: '{"FRESH_BUILD":"True", "UI":"True", "BUILD_BRANCH":"develop", "DEPLOY_DEV":"True"}'
        ...

和

name: Trigger Jenkins Build [ Build-Portal ]
on:
  push:
    branches: [ develop ]
    paths: 'backend/**'
    types: [closed]
jobs:
  build:
    name: Triggering Jenkins Build [ Build-Portal ]
    runs-on: ubuntu-latest
    if: github.event.pull_request.merged == true
    steps:
    - name: Trigger Build-Portal
      uses: actions/trigger-jenkins@develop
      with:
        ...
        job_name: "Build-Portal"
        job_params: '{"FRESH_BUILD":"True", "API":"True", "BUILD_BRANCH":"develop", "DEPLOY_DEV":"True"}'
        ...

我可以将这两个文件合并到一个工作流文件 (.github/workflows/) 中，还是需要为每个文件创建单独的文件？

注意：job_params 对于两个触发器来说是不同的。

【解决方案1】：

根据github action documentation，它应该在使用多个路径的同一工作流程中工作。

如果您还使用paths-filter action，您可以通过以下方式获得您想要的结果：

示例：

name: Trigger Jenkins Build [ Build-Portal ]
on:
  push:
    branches: [ develop ]
    paths: 
       - 'frontend/**'
       - 'backend/**'
    types: [closed]
jobs:
  build:
    name: Triggering Jenkins Build [ Build-Portal ]
    runs-on: ubuntu-latest
    if: github.event.pull_request.merged == true
    steps:
      - uses: dorny/paths-filter@v2
        id: changes
        with:
           filters: |
              backend:
                - 'backend/**'
              frontend:
                - 'frontend/**'
    - name: Trigger Build-Portal FRONTEND
      # run only if some file in 'frontend' folder was changed
      if: steps.changes.outputs.frontend == 'true'
      uses: actions/trigger-jenkins@develop
      with:
        ...
        job_name: "Build-Portal"
        job_params: '{"FRESH_BUILD":"True", "UI":"True", "BUILD_BRANCH":"develop", "DEPLOY_DEV":"True"}'
        ...
     - name: Trigger Build-Portal BACKEND
      # run only if some file not 'backend' folder was changed
      if: steps.changes.outputs.backend == 'true'
      uses: actions/trigger-jenkins@develop
      with:
        ...
        job_name: "Build-Portal"
        job_params: '{"FRESH_BUILD":"True", "API":"True", "BUILD_BRANCH":"develop", "DEPLOY_DEV":"True"}'
        ...

job_params 对于两个触发器是不同的。
抱歉，我在job_params 中没有看到UI 和API 的区别。在这种情况下，您可以使用 2 个具有不同 if 条件的作业，具体取决于所使用的路径。也可以使用paths-filter action
我用这个路径过滤器操作的例子更新了答案
感谢多尼/路径过滤器的指针；我用它解决了a similar filtering issue。
