Powershell Stdout не возвращается в Jenkins

1 голос
/ 19 июня 2020

Я работаю с Psexe c из-за некоторых ограничений компании в отношении PSremoting и WMI, а также из-за ненормального вывода PSexe c и определенных значений, интерпретируемых как код ошибки / код выхода в PowerShell. Я адаптировал оболочку из этого post .

Все работает нормально при вызове на локальном компьютере, но не stdout при вызове из этапа сборки Jenkins.

Я хотел бы сделать запрос для рабочего стола SessionID удаленной машины, и эти данные возвращаются в stdout. Есть ли способ сделать это с помощью оболочки, или мне понадобится прямой подход? Это действительно сработало, но я хотел иметь лучшую структуру и отчеты об ошибках во всех сценариях, используемых для сборки: 

$stdout = & $psexec \\$hostName -u $user -p $pass -accepteula cmd /c "tasklist /FI "IMAGENAME eq taskhost*" /FO List | findstr "Session#:""

Функция Get-SessionID: 

function Get-SessionID
{
<#
    .SYNOPSIS
    Get session ID.

    .DESCRIPTION
    Get the host machines desktop session ID.

    .PARAMETER None

# Import external functions
Push-Location $PSScriptRoot
Import-module .\Write-Log.ps1 -Force
Import-module .\CheckAndLoad-EnvironmentVariable.ps1 -Force
Import-module .\Psexec-Wrapper.ps1 -Force

# Check and load the environment variables
    $hostName = "<IP Address of the remote machine>"
    $psexec = "<Path to PSExec.exe>"
    $user = "<Remote Machine User Name>"
    $pass = "<Remote Machine Password>"
    $cmd = "-u $user -p $pass -accepteula -nobanner cmd /c tasklist /FI ""IMAGENAME eq taskhost*"" /FO List"

    Write-Log("Running the following command with PsExec: $psexec \\$hostName $cmd")

    # Call PsExec with the command line arguments
    $result = Psexec-Wrapper $psexec $hostName $cmd
    # Check if PsExec call was successful
if(!$? -or ($LASTEXITCODE -ne 0) -or ($result.session_id -eq "") -or ($result.session_id -eq "None"))
{
    $errorMessage = "Failed to get the session ID. Result: $logResult"
    Report-Error $errorMessage "-13"
    Pop-Location
    return
} 

# Process results
$logResult = $result | Out-String
Write-Log("PsExec output: $logResult")

#Report if error occurred
If($result.exit_code -ne 0)
{
    #Exit code for certain run issues should be -13 or Psexec specific error code
    $errorMessage = $result.std_err | Out-String
    Report-Error $errorMessage $result.exit_code
    Pop-Location
    return
}

# Get the ID from string
$sessionID= $result.session_id | Out-String

Pop-Location
return $sessionID
}

Вот код оболочки :
