Powershell Script not getting failed in Jenkins

Question

I have downloaded SSH-Sessions by Joakim Svendsen which uses SSH.NET and installed the PowerShell module in the Jenkins Windows server

In Jenkins, I have the following PowerShell script:

Import-Module SSH-Sessions

$lastExitCode = 0
$devApp1 = "10.0.0.1"
$devApp2 = "10.0.0.2"

Write-Output "Deployment started in $devApp1......"

New-SshSession -ComputerName $devApp1 -Username test -Password test@123
$return = Invoke-SshCommand -ComputerName $devApp1  -Command "cd /NFS_DATA/autodeploy_scripts && echo test@123 | ./autodeploy.sh"

$return | Get-Member

if ($lastExitCode -ne 0)
{
    Write-Output $lastExitCode
    exit 1;
}
else
{
    Write-Output $lastExitCode
    exit 0;
}

The shell script contains:

#!/bin/bash
file="/NFS_DATA/autodeploy_scripts/test.log"
if [ -f "$file" ]
then
        echo "$file found."
        exit 0;
else
        echo "$file not found."
        exit 1;
fi

The problem is that the Jenkins job doesn't get failed when the file is not found. The Jenkins output is:

> Deployment started in 10.0.0.1...... Successfully connected to
> 10.0.0.01
> 10.0.0.01 had an error:

Finished: SUCCESS

After some suggestions I wrote the following PowerShell script using Posh-SSH. I'm also getting an error for this one, though it's different.

#Import-Module SSH-Sessions
Import-Module Posh-SSH

# Setup static variables
$devApp1="10.0.0.1"
$devApp2="10.0.0.2"
$username = "test"
$password = "test@123"
$command = "cd /NFS_DATA/autodeploy_scripts && echo Hybris@123 | ./autodeploy.sh"

Write-Output "Deployment started in $devApp1..."

# Setup PSCredentials
$secPasswd   = ConvertTo-SecureString $password -AsPlainText -Force
$credentials = New-Object System.Management.Automation.PSCredential ($username, $secPasswd) 
echo $credentials

# Estalbish new SSH session automatically accepting new SSH keys
$session = New-SSHSession -Computername $devApp1 -Credential $credentials -Acceptkey:$true

# Invoke command to be run on/in the SSH session
$output = Invoke-SSHCommand -SSHSession $session -Command $command

Write-Output "Returned Output from the Command: "
Write-Output $output.Output
Write-Output "Last Exit Status: "
Write-Output $output.ExitStatus

Getting the error message as:

The same code works in my local laptop, but fails in the Jenkins server.

I think in Jenkins server, due to Windows security restrictions, will not store the $secpasswd that is retrieved from the PSCredential. This causes only the username to be supplied to POSH.

How can I either fix those issues? How should I hardcode the password?

As you've never stated where those commands are coming from, I'm going to assume you're using Posh-SSH. By looking at this article about it, the solution would probably be:

$dev_app1="10.00.00.01"
$dev_app2="10.00.00.02"

echo "Deployment started in $dev_app1......"
Import-Module SSH-Sessions
New-SshSession -ComputerName $dev_app1 -Username test -Password test@123
$result = Invoke-SshCommand -ComputerName $dev_app1  -Command "cd /NFS_DATA/autodeploy_scripts && echo test@123 | ./autodeploy.sh"

Write-Output "Returned Output from the Command: "
Write-Output $result.Output
Write-Output "Last Exit Status: "
Write-Output $result.ExitStatus

if($result.ExitStatus -ne 0){
    exit $result.ExitStatus;
}

The if could be left out, it's just there for demonstration purposes. After all the exit status would be 0 otherwise.

The correct way to use Get-Member to get information about $result (in case this does not work) would be: $result | Get-Member. That will output the general attributes of whatever kind of object $result is.

As it would appear you're running this. You would need to run the following to get the objects:

$result = $SshSessions."$dev_app1".RunCommand('cd /NFS_DATA/autodeploy_scripts && echo test@123 | ./autodeploy.sh')

You'd use this instead of the Invoke-SshCommand and would need to change $result.Output to $result.Result.
