Accessing the build revision number in Powershell script during TFS build

Question

I can get the build number from IBuildDetail.BuildNumber but this is taken from the build definition and there fore might not include the revision number $(Rev:.r) or it might not be at the end.

So I would like to get this number without having to parse it from the build number. Is this property available any where during the build?

Answer 1

Use the build variables.

From PowerShell use $Env:BUILD_BUILDNUMBER if you’re using TFS 2015.

See MSDN: Use a PowerShell script to customize your build process

For previous versions: Team Foundation Build environment variables

Answer 2

you can use following powershell script to parse Build number

[String]$myrev = $Env:BUILD_BUILDNUMBER
$result = $myrev.Substring($myrev.LastIndexOf('.') + 1)
Write-Host $result
