How to view script output (specifically PowerShell) from a Jenkinsfile? - powershell

Question

I'm pretty new to Jenkins, so not totally clear on how to assign/read variables.
I have a jenkinsfile with a couple stages and a bunch of steps. In one of the steps, I want to run a PowerShell script but it isn't accomplishing the intent. The problem is, when I'm in Jenkins and I go to the Console Output to troubleshoot why the PowerShell script isn't working, I don't see any of the output from the powershell script, I just see this:
[Pipeline] {
[Pipeline] powershell (Test PowerShell Script)
[Pipeline] }
Here's a trimmed-down version of my code:
stages {
stage('Stage 1') {
agent { node {
label "Windows"
customWorkspace "D:\\Path"
}}
steps {
dir('Directory') {
withCredentials(
[usernameColonPassword(
credentialsId: 'credential1',
variable: 'BasicCred'
)]
) {
powershell(
label: 'Test PowerShell Script',
returnStdout: true,
script: 'echo Test'
)
}
}
}
}
}
I tried using the code provided in this Jenkins article:
steps {
dir('Directory') {
withCredentials(
[usernameColonPassword(
credentialsId: 'credential1',
variable: 'BasicCred'
)]
) {
def msg = powershell(
label: 'Test PowerShell Script',
returnStdout: true,
script: 'echo Test'
)
println msg
}
}
}
This threw an error:
WorkflowScript: 135: Expected a step # line 135, column 25.
def msg = powershell(
^
I also tried putting it inside a node:
steps {
dir('Directory') {
node {
withCredentials(
[usernameColonPassword(
credentialsId: 'credential1',
variable: 'BasicCred'
)]
) {
def msg = powershell(
label: 'Test PowerShell Script',
returnStdout: true,
script: 'echo Test'
)
println msg
}
}
}
}
But it threw an error that the node is missing a label, and when I tried adding a label it threw another error.
So what's the right way to go about this? I just want to capture the output from the PowerShell script and see it so I can troubleshoot why it isn't working.
