如何使用 Azure devops 管道仅获取更改的文件

How to get only changed files using Azure devops pipelines

我在源代码中有这样的文件夹结构。 f1 f2 f3 f4

我在我的管道中添加了 gitcopy diff 任务,该任务列出并复制修改到目标文件夹的文件。 现在,我想有一个条件循环作为 powershell 脚本,只压缩那些修改了具有特定名称的文件的文件夹,例如,如果修改了来自 f1 的文件..我想执行特定的步骤等等..我怎么能做一个循环? 编辑:我用这种方式编写了我的管道。但是它在发布步骤中失败并出现所列错误。

没有现成的解决方案。但是您可以使用 REST API Commits - Get Changes 调用来检查:

GET https://dev.azure.com/fabrikam/_apis/git/repositories/278d5cd2-584d-4b63-824a-2ba458937249/commits/be67f8871a4d2c75f13a51c1d3c30ac0d74d4ef4/changes?top=2&skip=10&api-version=5.0

{
  "changeCounts": {
    "Add": 456
  },
  "changes": [
    {
      "item": {
        "gitObjectType": "blob",
        "path": "/MyWebSite/MyWebSite/favicon.ico",
        "url": "https://dev.azure.com/fabrikam/_apis/git/repositories/278d5cd2-584d-4b63-824a-2ba458937249/items/MyWebSite/MyWebSite/favicon.ico?versionType=Commit"
      },
      "changeType": "add"
    },
    {
      "item": {
        "gitObjectType": "tree",
        "path": "/MyWebSite/MyWebSite/fonts",
        "isFolder": true,
        "url": "https://dev.azure.com/fabrikam/_apis/git/repositories/278d5cd2-584d-4b63-824a-2ba458937249/items/MyWebSite/MyWebSite/fonts?versionType=Commit"
      },
      "changeType": "add"
    }
  ]
}

如果您使用 gitcopy diff task 并且您没有展平目标文件夹,您应该使用命令行分析您的目标文件夹 - powershell/bashh - 并基于此设置变量。

$f1Changed = ((Get-ChildItem -Path .\destination\f1\ | Measure-Object).Count -gt 0)

然后您可以分析此响应并检查更改的内容。基于此,您可以使用 logging command:

设置变量
Write-Host "##vso[task.setvariable variable=f1changed;]$f1Changed"

然后在此处的步骤中使用此变量来压缩此特定文件夹。

 condition: and(succeeded(), eq(variables.f1changed, true))

你可以在powershell任务git commands下面直接运行查看修改后的文件。它比 Rest api.

容易得多

git diff-tree --no-commit-id --name-only -r $(Build.SourceVersion)

当您获得更改的文件时,您可以使用 Compress-Archive 命令直接在 powershell 任务中使用 zip 更改的文件夹:参见下面的示例:

Compress-Archive -Path C:\f1 -DestinationPath f1.zip

如果您希望根据更改后的文件夹执行某些特定步骤。您可以定义标志变量并使用 logging commands in the powershell scripts to set the flags to true. And then use the condtions 进行以下步骤。

请参阅下面的完整示例脚本:

##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

然后您可以像 Krzysztof 提到的那样,将条件用于某些特定步骤

condition: and(succeeded(), or(eq(variables.f1Flag, true),eq(variables.f2Flag, true),eq(variables.f3Flag, true)))
