In this article I show you a PowerShell script which clones and pulls all Git repositories from your Azure DevOps collection. I use this script to retrieve the complete code base so that I can run my code analysis tools on it.

1. Create a new PowerShell script file

In the directory where you want to clone all repositories, create a new CloneAllRepos.ps1 script file with the following contents:

# Read configuration file
Get-Content "CloneAllRepos.config" | foreach-object -begin {$h=@{}} -process { 
    $k = [regex]::split($_,'='); 
    if(($k[0].CompareTo("") -ne 0) -and ($k[0].StartsWith("[") -ne $True)) { 
        $h.Add($k[0], $k[1]) 
$url = $h.Get_Item("Url")
$username = $h.Get_Item("Username")
$password = $h.Get_Item("Password")

# Retrieve list of all repositories
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))
$headers = @{
    "Authorization" = ("Basic {0}" -f $base64AuthInfo)
    "Accept" = "application/json"

Add-Type -AssemblyName System.Web
$gitcred = ("{0}:{1}" -f  [System.Web.HttpUtility]::UrlEncode($username),$password)

$resp = Invoke-WebRequest -Headers $headers -Uri ("{0}/_apis/git/repositories?api-version=1.0" -f $url)
$json = convertFrom-JSON $resp.Content

# Clone or pull all repositories
$initpath = get-location
foreach ($entry in $json.value) { 
    $name = $entry.name 
    Write-Host $name

    $url = $entry.remoteUrl -replace "://", ("://{0}@" -f $gitcred)
    if(!(Test-Path -Path $name)) {
        git clone $url
    } else {
        set-location $name
        git pull
        set-location $initpath

2. Create configuration file

Now, create a CloneAllRepos.config file alongside your ps1 script with your configuration:


If you use two-factor authentication, you need to generate a password on the Azure DevOps site: Go to User Settings > Security > Personal access tokens, create an access token and use it as password in the configuration file.

3. Execute script

To execute the script in the Windows or PowerShell command prompt, run the following command:

powershell -ExecutionPolicy Bypass -File ./CloneAllRepos.ps1

If you’d like to execute the script without bypassing the policy in each call, you have to enable script execution globally:

Set-ExecutionPolicy Unrestricted

Now, you can execute the script in the PowerShell command line in this way:
