How to sync local changes to a SECOND Git repository?

I was able to get this working using a combination of these answers:

The trick is to use the Personal Access Token (PAT), found in the security section of the VSTS user profile.

Here're the scripts I ended up with:

SyncCode.ps1, called from the build step

[CmdletBinding()] param( [Parameter(Mandatory)][string] $Application, [Parameter(Mandatory)][string] $LocalPath, [Parameter(Mandatory)][string] $Token ) . \\SERVER\Scripts\TfsBuild\Invoke-Git.ps1 $RemoteExists = $false $AllRemotes = git remote ForEach($Remote in $AllRemotes) { If($Remote = $Application) { $RemoteExists = $true Break } } If($RemoteExists) { Invoke-Git -Command "remote remove $Application" } Invoke-Git -Command "remote add $Application https://Personal%20Access%20Token:[email protected]/Applications/_git/$Application" Set-Location $LocalPath Invoke-Git -Command "push --mirror HydraMonitor" 

Invoke-Git.ps1, called from SyncCode.ps1

<# .Synopsis Invoke git, handling its quirky stderr that isn't error .Outputs Git messages, and lastly the exit code .Example Invoke-Git push .Example Invoke-Git "add ." #> Function Invoke-Git { param( [Parameter(Mandatory)] [string] $Command ) Write-Output "##[command]. git $Command" Try { $Exit = 0 $Path = [System.IO.Path]::GetTempFileName() Invoke-Expression "git $Command 2> $Path" $Exit = $LASTEXITCODE If ( $Exit -gt 0 ) { Write-Error (Get-Content $Path).ToString() } Else { Get-Content $Path } "Exit code: $Exit" } Catch { Write-Host "Error: $_`n$($_.ScriptStackTrace)" } Finally { If ( Test-Path $Path ) { Remove-Item $Path } } }
