Getting output values from powershell script from jenkins pipeline

Modify your Get-GUID.ps1 script to write output to one file or multiple files and retrieve value from them.

Your Get-GUID.ps1 file will look like this:

$buildguid = (New-Guid).Guid$name = "Tom"Write-Output $buildguid | Out-File "buildguid.txt"Write-Output $name | Out-File "name.txt"

The output can be retrieved from the pipeline like this:

pipeline {    agent { label 'windows' }    stages {        stage("Populate variables")        {            steps {                script {                    def result = powershell returnStatus:true, script: '.\\Get-GUID.ps1'                }            }        }                stage("Display variables")        {            steps {                script {                    def guid = powershell returnStdout:true, script: 'Get-Content .\\buildguid.txt'                    def name = powershell returnStdout:true, script: 'Get-Content .\\name.txt'                    print guid.trim()                    print name.trim()                }            }        }    }}

Note: Don't forget to trim() your output when retrieved.
