其他-How to get only changed files using Azure devops pipelines

Levi Lu-MSFT 2020-12-03 14:40:14

You can directly run below git commands in the powershell task to check the changed files. It is much easier than Rest api.

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

When you get the changed files, you can use the zip the changed folders directly in the powershell task using Compress-Archive command: See below example:

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

If you want some particular steps to be performed based on the the changed folders. You can define the flag variables and using the logging commands in the powershell scripts to set the flags to true. And then use the condtions for the following steps.

See below full example scripts:

##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

Then you can use the condition for some particular steps just as Krzysztof mentioned

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

See the answer to this thread for more information.

Update:

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)))

Hi, could u check my edit? I have made changes to the pipeline.Now its failing in the condition statement

Levi Lu-MSFT 2020-12-02 07:18:17

@priya You can must use stage under stages section. you can use condtions for steps. no need to use stage. See above update

@priya How was it going? Did it work out?

priya 2020-12-02 09:49:01

@ lEVI, thankyou..could u pls tell me how can I add multiple conditions here? I want the publish task to run when either f1 or f2 or f3 flag turns true..

@priya You can use or expression. See above updated. Check here for more information.
