Execute powershell script on a linux Jenkins server from groovy pipeline file? - linux

Question

So after spending half a day as our surprise jenkins devops guy, I'm not sure if this scenario is even possible.
We have a linux Jenkins server that runs a groovy file to build some of our software. Recently we moved from dropbox to onedrive and one of my tasks is to change all our CI apps to upload files to onedrive. Using appveyor and powershell I was able to do this, but Jenkins is giving me problems. I was hoping to re-use the powershell scripts I wrote for appveyor, tweak them, and use them in the Jenkins pipeline. I've installed the Powershell plugin on our Jenkins server, but it's still not finding powershell. I've tested the GetAccessToken.ps1 script locally (but I'm on w10), and it's fine.
Groovy code snippet
stage('Deploy')
{
environment
{
ONEDRIVE_ID = credentials('OneDriveClientId')
ONEDRIVE_SECRET = credentials('OneDriveSecretKey')
ONEDRIVE_TOKEN = powershell "Common/Build/GetAccessToken.ps1 ${ONEDRIVE_ID} ${ONEDRIVE_SECRET}"
}
steps
{
echo 'Deploying Code....'
sh "chmod +x Common/Build/UploadToOnedrive.ps1"
powershell "Common/Build/UploadToOnedrive.ps1 -t ${ONEDRIVE_TOKEN} -s bootloader/redacted/Build/redacted-f redacted -v ${VERSION} -b ${BRANCH_NAME}"
}
}
Error
Caused: java.io.IOException: Cannot run program "powershell" (in directory "/var/lib/jenkins/workspace/test_branch"): error=2, No such file or directory
I've tried about 10 different ways of calling the script, based on other SO posts and jenkins.io posts, and I get varying degrees of failure. I'm wondering if I need a Windows slave to run powershell (although I thought the plugin would allow me to). Last resort I'll just try to alter the old bash scripts to upload using curl but I was really hoping to use the powershell scripts.
Oh, and here's my PATH. I think I read that pwsh/powershell gets installed in /usr/local/sbin or /usr/local/bin so that shouldn't be the issue
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

Thanks to Shane's sanity check, I was able to install pwsh on the Jenkins ubuntu server and then my groovy pwsh steps started working. I'm still having some issues passing variables but that's for another topic. I'm now able to use scripts like this in my groovy script
environment {
ONEDRIVE_TOKEN = pwsh (script: "Common/Build/GetAccessToken.ps1 ${env.ONEDRIVE_ID} ${env.ONEDRIVE_SECRET}", returnStdout: true)
}
Update; here is how I'm able to call a powershell script from groovy with variables
sh 'pwsh Common/Build/UploadToOnedrive.ps1 -t $ONEDRIVE_TOKEN -s "Release" -f "testname" -v $VERSION -b $BRANCH_NAME'
