I use Jenkins and pipeline Jenkinsfile with a Windows agent. I want set a veriable from powershell in a 1st step and use this value in a 2nd step after.
my pipeline is:
def MSVERSION
pipeline {
stages {
stage('Clean workspace') {
steps {
deleteDir()
}
}
stage('package') {
steps {
script {
def stdout = powershell(returnStdout: true, script: '''
$MSVERSION="1234"
write-host "MSVERSION is $MSVERSION"
''')
println stdout
}
}
}
stage('deploy') {
steps {
script {
bat 'echo MSVERSION is ${MSVERSION}'
}
bat 'echo MSVERSION is ${MSVERSION}'
}
}
}
}
but my result is:
MSVERSION is 1234
MSVERSION is ${MSVERSION}
MSVERSION is ${MSVERSION}
EDIT
I find a workaroud but is not my question today:
in powershell I write a var.propertie file:
set-Content -path "var.properties" -Value "MSVERSION=$($VERSION)"
and in my script I read this var.properties file:
properties = readProperties file: 'var.properties'
echo "MSVERSION is ${properties.MSVERSION}"
bat 'echo MSVERSION is ${MSVERSION}'
does not do string interpolation, but this does:
bat "echo MSVERSION is ${MSVERSION}"

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.
I am trying to execute a process which is written in c# through jenkins pipeline during the build and deployment process.
It is a simple executable which takes 3 arguments, when it gets called from jenkins pipeline using a powershell function it doesn't write any logs which are plenty within the code of this exe, also it does not show anything on the pipeline logs as to what happened to this process. Whereas the logs output is clean before and after the execution of this process i.e. "Started..." & "end" gets printed in the jenkins build log.
When i try to run the same exe on a server directly with the same powershel script it runs perfectly fine. Could you please let me know how can i determine whats going wrong here or how can i make the logs more verbose so i can figure out the root cause.
Here is the code snippet
build-utils.ps1
function disable-utility($workspace) {
#the code here fetches the executable and its supporting libraries from the artifactory location and unzip it on the build agent server.
#below is the call to the executable
Type xmlPath #this prints the whole contents of the xml file which is being used as an input to my exe.
echo "disable exe path exists : $(Test-Path ""C:\Jenkins\workspace\utils\disable.exe"")" // output is TRUE
echo "Started..."
Start-Process -NoNewWindow -Filepath "C:\Jenkins\workspace\utils\disable.exe" -ArgumentList "-f xmlPath 0" #xmlPath is a path to a xml file
echo "end."
}
jenkinsfile
library {
identifier: 'jenkins-library#0.2.14',
retriever: legacySCM{[
$class: 'GitSCM',
userRemoteConfigs: [[
credtialsId: 'BITBUCKET_RW'
url: <htps://gitRepoUrl>
]]
]}
}
def executeStep(String stepName) {
def butil = '.\\build\\build-utils.ps1'
if(fileExists(butil))
{
def status = powershell(returnStatus: true, script: "& { . '${butil}'; ${stepName}; }")
echo status
if(status != 0) {
currentBuild.Result = 'Failure'
error("$StepName failed")
}
}
else
{
error("failed to find the file")
}
}
pipeline {
agent {
docker {
image '<path to the docker image to pull a server with VS2017 build tools>'
lable '<image name>'
reuseNode true
}
}
environment {
#loading the env variables here
}
stages {
stage {
step {
executeStep("disable-utility ${env.workspace}")
}
}
}
}
Thanks a lot in advance !
Have you changed it ? go to Regedit [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System Set "EnableLUA"= 0
I trying to define powershell variable inside jenkins pipeline with the WORKSPACE variable in value. Is there a way to do this?
stage ('BUILD') {
steps {
powershell ("""Write-Output ${WORKSPACE}\\One\\Two\\""")
}
}
Output:
[Pipeline] powershell
18:18:15 C:\buildenv\Jenkins\workspace\project\One\Two\
[Pipeline] }
[Pipeline] // stage
That's nice. Now i need to wrap it into variable:
stage ('BUILD') {
steps {
powershell ("""$name02=${WORKSPACE}\\One\\Two\\""")
}
}
Output now:

How do I pass my variable VAR_A to an embedded powershell script in a jenkins pipeline ?
e.g.
def VAR_A = 'test'
def mystatus = powershell(returnStatus: true, script: '''
Write-Host "My result: '$VAR_A'" '''
withEnv(["VAR_A=test"]) {
def mystatus = powershell(returnStatus: true, script: '''
Write-Host "My result: '$VAR_A'" '''
}
both result with following output
My result: ''
Note : I prefer to define my powershell script in the jenkinsfile to keep things simple.
Try this:
node {
powershell '''
$VAR_A = 'test'
Write-Host "My result: '$VAR_A'"
'''
withEnv(["VAR_A=envtest"]) {
powershell '''
Write-Host "My result is empty: '$VAR_A'"
Write-Host "My env result: '$env:VAR_A'"
'''
}
}
The output is:
My result: 'test'
My result is empty: ''
My env result: 'envtest'
This was tested on Jenkins 2.73.1.
Note that:
$VAR_A = 'test' is declared within the first powershell '''...'''
env: is required to access environment variables (see about_Environment_Variables in the Microsoft Docs)
I am trying in a powershell psake script to execute a .bat file. Is this possible? Or do I have to do a workaround?
Try the following:
task CallBatch {
exec {cmd.exe /c "path\to\my\testscript.bat"}
}
It is not necessary to wrap the call to cmd.exe in PSake's exec {} function, but if you do it, the build fails if the batch returns anything but 0.
The task below always lets the build fail:
task Return1FromCmd {
exec {cmd.exe /c "#exit 1"}
}
To execute a .bat (or .cmd) from PowerShell:
foo.bat:
#echo off
echo "foo"
foo.ps1:
. .\foo.bat
#or
.\foo.bat
#or
& .\foo.bat
we can then run the script:
D:\dev> .\foo.ps1
"foo"
This works for me:
properties {
$mybat = 'C:\path\tool.bat'
}
task Test -depends ... {
"Bla bla"
Exec { & $mybat }
}
No need to directly mention cmd.exe -- using & in the Exec script block seems to be enough.
