您可以在Powershell脚本中使用label参数来过滤特定文件，然后运行git命令，然后复制并发布通过label参数过滤的特定文件，如下图所示：

我的Yaml脚本与PowerShell和发布任务：-

trigger:
- '*'

pool:
  vmImage: 'windows-latest'

steps:
- powershell: |
    # Step 1: Identify Files Containing 'package.json'
    $label = "package.json"
    $filesToCopy = Get-ChildItem -File | Where-Object { (Get-Content $_.FullName) -like "*$label*" }

    # Step 2: Copy Selected Files
    $destinationDirectory = "$(Build.ArtifactStagingDirectory)"
    foreach ($file in $filesToCopy) {
        $destinationFile = Join-Path -Path $destinationDirectory -ChildPath $file.Name
        Copy-Item -Path $file.FullName -Destination $destinationFile
    }
  displayName: 'Run PowerShell Script'

- task: PublishBuildArtifacts@1
  inputs:
    pathtoPublish: '$(Build.ArtifactStagingDirectory)'
    artifactName: 'selected-files'
    publishLocation: 'Container'

输出：-
