Update TFS 2012 Project Build definition after migrating from TFS 2008 via PowerShell

In this post, I just want to help those of you out there that have upgraded from 2008 and need to bulk update all of your build definitions. In this particular example, I will be updating the Build Controller, Drop location and Agent Settings of the build.

Here's is the main PS file which iterates through all projects in a specified TPC and call another PS to do the meat work..

param

(

[string] $TfsServerUri = http://TFS:8080/tfs/TPC)

$TfsSnapin = Get-PSSnapin -Name Microsoft.TeamFoundation.PowerShell -ErrorAction SilentlyContinue

if ($TfsSnapin -eq $null)

{

    Add-PSSnapin Microsoft.TeamFoundation.PowerShell

}

## Local Variables

$CurrentExecutionDir = Split-Path -parent $MyInvocation.MyCommand.Definition

[string] $LogFile = "$CurrentExecutionDir\PSSessionLog.txt"

##

If(Test-Path $LogFile) { Remove-Item -Path $LogFile }

##Connect Tfs

$TfsServer = Get-TfsServer -Name $TfsServerUri

try

{

    $TfsServer.EnsureAuthenticated()

}

catch

{

    Write-Error "Error occurred trying to connect to project collection: $_ "

    Exit-PSSession

}

##

## Enumerate all Tfs projects and perform update on build definitions

$CssService = $TfsServer.GetService([Microsoft.TeamFoundation.Server.ICommonStructureService3])

$TfsProjectList = $CssService.ListAllProjects()

foreach($teamProject in $TfsProjectList)

{

    try

    {

        .{."$CurrentExecutionDir\Update-BuildDefinitions.ps1" -TFSServerInstance $TfsServer - ProjectName $teamProject.Name -LogFile $LogFile}

    }

    catch

    {

        Write-Host ($_) -ForegroundColor Red

        Out-File $LogFile -InputObject $_ -Append

    }

}

##

Remove-PSSnapin Microsoft.TeamFoundation.PowerShell

And here is the crux PS which does the real work of updating build definitions called Update-BuildDefinitions.ps1

This PS file should be located beside the main PS file.

 

param(

$TFSServerInstance,

[string] $ProjectName,

[string] $DefaultBuildControllerName = 'ControllerNew,

[string] $DefaultBuildDropLocation = '\\IT\Temp\Build',

)

        if($ProjectBuildDefinition.FullPath.Length -gt 0)

        {

        Write-Host ($Msg) -ForegroundColor Red

        throw

    }
