Gabriel Loewen, I determined the difference was because it was loading the PowerShell Profile for the user the build agent was executing as. I'll spin this off to another issue at this point (following Jesse's guidance). It will probably be an improvement to optionally set the -NoProfile flag when calling the PowerShell executable.

Gabriel Lopez I am using Write-Host in my powershell script but dont see any output in console. Do you know if there is any other way to produce console output.

Write-Host does not produce any output that can be consumed (e.g. written to the log). You can simply replace all of your calls to Write-Host with calls to Write-Output.

Here's a few things to read to understand why this is the behavior of Write-Host:

Gabriel Loewen Running powershell in the Jenkins Pipeline is hardcoded to use no profile. The powershell plugin defaults to the opposite. Can this be made configurable?
