仅构建在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，

  ProjectA.csproj 
 projectB.csproj 
 projectC .csproj 
  

我已经使用Master Branch的触发器为此解决方案创建了YAML CI构建管道

触发：-主人

只要上述任何项目的主人签到，它都会触发

问题-我只能使用相同的单个YAML文件来构建具有更改的项目吗？

问题？ p>

解决方案

问题-我只能使用相同的
单个YAML文件来构建具有更改的项目吗？解决方案？

是的，您可以。假设您有多个职位/步骤用于不同的项目，则可以使用条件来确定何时应运行/跳过一些特定步骤。您可以检查以下示例：

 触发：
-主
 
池：
 vmImage：'windows-latest'
 
步骤：
-任务：PowerShell @ 2 
输入：
 targetType：'inline'
脚本： | 
 $ 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这是$ name文件 
 if（$ name -like ProjectA / *）
 {
 Write-Host ## vso [task.setvariable variable = RunProjectA] True 
} 
 if（ $ name -like ProjectB / *）
 {
写主机 ## vso [task.setvariable variable = RunProjectB] True 
} 
 if（$ name-如 ProjectC / *）
 {
写主机 ## vso [task.setvariable variable = RunProjectC] True 
} 
} 
 
-脚本：echo更改ProjectA文件夹时运行此步骤。 
 displayName：'运行A'
条件：eq（variables ['RunProjectA']，'True'）
 
-脚本：echo更改ProjectB文件夹后运行此步骤。 
 displayName：'运行B'
条件：eq（variables ['RunProjectB']，'True'）
 
-脚本：echo更改ProjectC文件夹后运行此步骤。 
 displayName：'Run C'
条件：eq（variables ['RunProjectC']，'True'）
  

然后，如果我们仅在 ProjectA 文件夹中进行更改，则只有那些具有条件的步骤/任务：eq（variables [' RunProjectA']，'True'）将运行。您应该在管道中为 ProjectA ， ProjectB 和 ProjectC 进行三个单独的构建任务。 code>，并为他们提供自定义条件，那么您只能构建有更改的项目...（来自Jayendran 的提示a / 53229588/10910450>此问题！）

希望它能起作用。

I have multiple projects under a solution,

ProjectA.csproj
projectB.csproj
projectC.csproj

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

"trigger: - Master"

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.

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

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

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')

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!)

Hope it works.
