仅构建解决方案中更改的项目 -Azure CI 管道 - YAML [英] Build only projects which are changed in a solution -Azure CI pipeline - YAML

问题描述

我在一个解决方案下有多个项目，

I have multiple projects under a solution,

ProjectA.csproj
projectB.csproj
projectC.csproj

我已经为此解决方案创建了一个 YAML CI 构建管道，其中包含来自主分支的触发器

I have created a YAML CI build pipeline for this solution with trigger from Master Branch

触发器:-大师"

每当 Master 签入上述任何项目时，它都会触发 CI 管道并为上述所有单个项目创建工件.

Whenever a check-in happens to Master for any of the project above, it triggers the CI pipeline and create artifacts for all the above individual projects.

问题 - 我能否仅使用同一个 YAML 文件为解决方案构建有更改的项目?

Question - can I only build projects which have changes using the same single YAML file for the solution?

推荐答案

问题 - 我只能使用相同的方式构建具有更改的项目吗?解决方案的单个 YAML 文件?

Question - can I only build projects which have changes using the same single YAML file for the solution?

是的，你可以.假设您有多个 jobs/steps 用于不同的项目，您可以使用 Conditions 以确定何时应该运行/跳过一些特定步骤.你可以看看这个例子:

Yes, you can. Assuming you have multiple jobs/steps for different projects, you can use Conditions to determine when it should run/skip some specific steps. You can check this example:

trigger:
- master

pool:
  vmImage: 'windows-latest'

steps:
- task: PowerShell@2
  inputs:
    targetType: 'inline'
    script: |
      $files=$(git diff HEAD HEAD~ --name-only)
      $temp=$files -split ' '
      $count=$temp.Length
      For ($i=0; $i -lt $temp.Length; $i++)
      {
        $name=$temp[$i]
        echo "this is $name file"
        if ($name -like "ProjectA/*")
          {
            Write-Host "##vso[task.setvariable variable=RunProjectA]True"
          }
        if ($name -like "ProjectB/*")
          {
            Write-Host "##vso[task.setvariable variable=RunProjectB]True"
          }
        if ($name -like "ProjectC/*")
          {
            Write-Host "##vso[task.setvariable variable=RunProjectC]True"
          }
      }

- script: echo "Run this step when ProjectA folder is changed."
  displayName: 'Run A'
  condition: eq(variables['RunProjectA'], 'True')

- script: echo "Run this step when ProjectB folder is changed."
  displayName: 'Run B'
  condition: eq(variables['RunProjectB'], 'True')

- script: echo "Run this step when ProjectC folder is changed."
  displayName: 'Run C'
  condition: eq(variables['RunProjectC'], 'True')

那么如果我们只在 ProjectA 文件夹中进行更改，那么只有那些 condition: eq(variables['RunProjectA'], 'True') 的步骤/任务会运行.您应该在 ProjectA、ProjectB 和 ProjectC 的管道中有三个单独的构建任务，并为它们提供您的自定义条件，然后您只能构建有变化的项目...(来自 this issue 中的 Jayendran 的提示！)

Then if we only have changes in ProjectA folder, only those steps/tasks with condition: eq(variables['RunProjectA'], 'True') will run. You should have three separate build tasks in your pipeline for ProjectA, ProjectB and ProjectC, and give them your custom condition, then you can only build projects which have changes... (Hint from Jayendran in this issue!)

希望它有效.
