Uploading 2 files with same name to FTP using powershell script - powershell

Question

I am a beginner at powershell script and I am stuck
I am trying to upload 2 xml files with the same name to FTP, but I am getting the following error
Exception calling "UploadFile" with "2" argument(s): "An
exception occurred during a WebClient request." At
C:\powershell\ExternalWidgets\upload-to-ftp.ps1:51 char:16
+ $webclient.UploadFile($uri.AbsoluteUri, $LocalPath)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : WebException`
Here is the script:
#SET CREDENTIALS
$credentials = new-object System.Net.NetworkCredential($user, $pass)
cd $target
$DirectoryContent = Get-ChildItem -Directory
foreach($item in $DirectoryContent){
cd $item
$currentFolderItems = Get-ChildItem
foreach( $subfolderItem in $currentFolderItems)
{
if ($subfolderItem.name -eq "package.json") {
$subItem = Get-ChildItem -Directory
foreach($subItem in $subItem)
{
if ($subItem.name -eq "coverage") {
$files = Get-ChildItem -Path $subItem
$n = 0
foreach ($file in $files)
{
#rename coverage file
if($file.Name -eq "cobertura-coverage.xml") {
$newFileName=$file.Name.Replace("cobertura-coverage.xml","cobertura-coverage$n.xml")
Rename-Item $file -NewName $newFileName
$newFileName
}
$n++
}
}
}
$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object
System.Net.NetworkCredential($user,$pass)
$uri = New-Object System.Uri($ftp + "/" + $folder)
#Delete files from FTP
# $fileUploaded =($uri + "\" + $newFileName)
# $fileUploaded
# Remove-Item $fileUploaded
$LocalPath =($target + "\" + $item + "\" + "coverage" + "\" +
$newFileName).Replace(".\", "").Replace('\', '/')
$webclient.UploadFile($uri, $LocalPath)
#cd..
}
}
cd ..
}
I also get an error when I want to rename one of the files. What step am I missing? Thank you
