如何使用AzureDevOps管道仅获取更改的文件

我在源代码中有这种方式的文件夹结构。f1 f2 f3 f4

我在我的管道中添加了 gitcopy diff 任务，它列出并复制修改到目标文件夹的文件。现在，我想要一个条件循环作为 powershell 脚本来只压缩那些修改过具有特定名称的文件的文件夹，例如，如果 f1 中的文件被修改......我想要执行特定的步骤等等......我怎么能做一个循环？编辑：我以这种方式编写了我的管道。但是它在发布步骤中失败并列出了错误。

yaml: 触发器:

none

pool:
  vmImage: 'windows-latest'

variables:
  FR1PHPPRDAPP1VFlag: false
  FR1PHPPRDAPP4VFlag: false
  FR1PHPPRDAPP5VFlag: false
  FR1PHPPRDSRE1VFlag: false
  FR1PHPPRDAPP7VFlag: false

##set flag variables to indicate if the folder is changed.

variables:
  f1Flag: false
  f2Flag: false
  f3Flag: false
  
steps:

- powershell: |
      ## get the changed files
      $files=$(git diff-tree --no-commit-id --name-only -r $(Build.SourceVersion))
      $temp=$files -split ' '
      $count=$temp.Length
      echo "Total changed $count files"
     
      For ($i=0; $i -lt $temp.Length; $i++)
      {
        $name=$temp[$i]
        echo "this is $name file"
        if ($name -like 'f1/*')  #if f1 is a subfolder under a folder use "- like '*/f1/*'"
        { 
          ##achive folder f1 if it is changed.
          ##Compress-Archive -Path $(system.defaultworkingdirectory)/f1 -DestinationPath $(Build.ArtifactStagingDirectory)/f1.zip
          
          ##set the flag variable f1Flag to true
          Write-Host "##vso[task.setvariable variable=f2Flag]true"
        }
        if ($name -like 'f2/*')
        {
          ##achive folder f2 if it is changed.
          ##Compress-Archive -Path $(system.defaultworkingdirectory)/f2 -DestinationPath $(Build.ArtifactStagingDirectory)/f2.zip
          ##set the flag variable f2Flag to true
          Write-Host "##vso[task.setvariable variable=f2Flag]True"
        }
      }
      ## create a temp folder to hold the changed files
      New-Item -ItemType directory -Path $(system.defaultworkingdirectory)temp

      foreach($file in $temp){
        if(Test-Path -path $file){
        Copy-Item -Path $file -Destination $(system.defaultworkingdirectory)temp
        }
      }
      ## zip the temp folder which only have the changed files
      Compress-Archive -Path $(system.defaultworkingdirectory)temp* -DestinationPath $(Build.ArtifactStagingDirectory)changedfiles.zip

steps:

- powershell: |
     #get the changed files
     ....

        
- task: PublishBuildArtifacts@1
  inputs:
     PathtoPublish: '$(Build.ArtifactStagingDirectory)/Output'
     ArtifactName: 'drop'
     publishLocation: 'Container'
  condtion: and(succeeded(), or(eq(variables.f1Flag, true),eq(variables.f2Flag, true),eq(variables.f3Flag, true)))
