Pass bool param to a powershell script in Jenkinsfile multiline parameterised pipeline - powershell

Question

In my Jenkinsfile I have something like:
def addDollar(param) {
return "\$" + param
}
parameters {
booleanParam(
defaultValue: false,
name: 'FORCE_UPGRADE'
)
}
environment {
FORCE_UPGRADE = addDollar(params.FORCE_UPGRADE)
}
stages {
stage('Test') {
steps {
powershell script: ".\\test.ps1 -forceUpgrade ${env:FORCE_UPGRADE}"
}
}
stage('Test Multiline') {
steps {
powershell script: '''
.\\test.ps1 `
-forceUpgrade $env:FORCE_UPGRADE
'''
}
}
}
and the powershell script is
param (
[Parameter(Mandatory=$true)][boolean]$forceUpgrade=$false
)
if($forceUpgrade) {
Write-Host "Forcing upgrade"
}
This jenkins stage Test works as expected but Test Multiline erorrs with ParameterBindingArgumentTransformationException:
Cannot process argument transformation on parameter 'forceUpgrade'. Cannot convert value "System.String" to type "System.Boolean". Boolean parameters accept only Boolean values and
numbers, such as $True, $False, 1 or 0.
I get the same error if I run
.\test.ps1 -forceUpgrade false rather than
.\test.ps1 -forceUpgrade $false
Any ideas how to get the Jenkins Test Multiline stage working? I have a script where i need to pass a number of args, would be ideal to prevent horizontal scrolling using multiline powershell

Answer 1

Change the powershell input to a [string] instead of a [boolean]
[string]$forceUpgrade = $false
you will still be able to use the $forceUpgrade variable as a bool in the conditional in the powershell also.
