Download artifact from Jenkins using PowerShell

Question

I try download artifact from Jenkins using PowerShell, like this:

$webClient = new-object System.Net.WebClient 
$webClient.Credentials = New-Object System.Net.NetworkCredential ("username", "password")
$url = "http://jenkins/job/jobName/lastSuccessfulBuild/artifact/*zip*/archive.zip" 
$localfilename = "C:\Test\archive.zip"  
$webClient.DownloadFile($url, $localfilename)

I get exception:

Exception calling "DownloadFile" with "2" argument(s): "The remote server retur ned an error: (403) Forbidden." At C:\ps2.ps1:20 char:28 + $webclient.DownloadFile <<<< ($url, $localfilename) + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException

If I try download artifact using wget it works:

wget --auth-no-challenge --http-user=username --http-password=password http://jenkins/job/jobName/lastSuccessfulBuild/artifact/*zip*/archive.zip

If I using wget without parameter --auth-no-challenge I get the same error - Forbidden.

Using this authorization in request header is working great:

# Create web client with authorization header
$webClient = new-object System.Net.WebClient 
$credentialAsBytes = [System.Text.Encoding]::ASCII.GetBytes($userName + ":" + $password)
$credentialAsBase64String = [System.Convert]::ToBase64String($credentialAsBytes);
$webClient.Headers[[System.Net.HttpRequestHeader]::Authorization] = "Basic " + $credentialAsBase64String;
