Powershell script in declarative jenkins pipeline

In case someone is here, and still trying to figure out what is the issue. I will share the solution that worked for me.

Use escaping before variable "$" sign in multi-line string.

powershell ("""    \$psw = ConvertTo-SecureString -String \$CREDENTIAL_PSW -AsPlainText -Force    \$mySecureCreds = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList \$CREDENTIAL_USR, \$psw -Verbose    Set-Item WSMan:/localhost/Client/TrustedHosts -Value "*" -Force    \$session = New-PSSession -ComputerName "192.111.111.111" -Credential \$mySecureCreds""")

At the moment you're running each line in its own powershell process, so the results of the line before are not available to the next command.

I think you just need to move the script into a multi-line string:

powershell ("""    $psw = ConvertTo-SecureString -String $CREDENTIAL_PSW -AsPlainText -Force    $mySecureCreds = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $CREDENTIAL_USR, $psw -Verbose    Set-Item WSMan:/localhost/Client/TrustedHosts -Value "*" -Force    $session = New-PSSession -ComputerName "192.111.111.111" -Credential $mySecureCreds""")

You can easily run multiline powershell commands in jenkins pipeline like this. Example, if you want to login to azure using service principal, you'll do something like below:

powershell '''            $pass = ConvertTo-SecureString your_client_secret -AsPlainText –Force            $cred = New-Object -TypeName pscredential –ArgumentList your_client_id, $pass            Login-AzureRmAccount -Credential $cred -ServicePrincipal –TenantId your_tenant_id            -vaultName "eusdevmbe2keyvault" -name "normalizedcontainername").SecretValueText           '''
