VSTS missing certain build flag: env:BUILD_SOURCEV

Question

In my Visual Studio Team Services build I am pulling from a bitbucket repo. I am trying to get the commit message and use it in a powershell script.

In my powershell script I have the following code.

 param (
    ##Expect to be passed parameter $(Build.SOURCEVERSIONMESSAGE)
    [string]$commitMessage = ""
 )

Write-Warning "Source Message: $commitMessage"
Write-Warning "SOURCEVERSIONMESSAGE: $env:Build_SOURCEVERSIONMESSAGE"
Get-ChildItem Env:

Which gives me the following error:

2017-08-24T02:18:27.0938681Z ##[command]. 'd:\a\1\s\Pcmtec.Azure\DeploymentScripts\SetBuildTagTest.ps1' -commitMessage $(Build.SOURCEVERSIONMESSAGE)

It then prints out all the env variables. The only ones I get are:

Why is BUILD_SOURCEVERSIONMESSAGE missing?

Answer 1

Why is BUILD_SOURCEVERSIONMESSAGE missing?

I don't know, but it was reported missing before, as you noted (and in mentioned here as well).

I would still use the Git command alternative git log --format='%s' -1: if there is no value here either, that would at least give a clue.
