Copy-Item : The process cannot access the file - web-services

Question

I have a Jenkins job which does below activity.
Stop WebService
Delete WebService
Copy items from Jenkins workspace to server path
Create WebService
Start WebService
Below is my PowerShell script:
Get-ChildItem "C:\Location\*"
$service = Get-Service -Name value -Computername $env:SERVER -ErrorAction SilentlyContinue
sc.exe \\$env:SERVER stop value
Write-Host "value STOPPED"
sc.exe \\$env:SERVER delete val
Write-Host "val DELETED"
Copy-Item "C:\Location\*" "\\$env:SERVER\d$\Location" -Force -Recurse
sc.exe \\$env:SERVER create val start=auto DisplayName ="val" binPath= D:\Location.exe
sc.exe \\$env:SERVER description value"value"
sc.exe \\$env:SERVER start value
Write-Host "value STARTED"
if ($error) { exit 1 }
Error logs:
Copy-Item : The process cannot access the file '\\Location' because it is being used by another process.

Can you please help me out with this error? Do I need to restart the deploy server so that my process gets killed? If so I feel this is not relevant and cannot do in prod servers.

Answer 1

The problem is that you have another process which is using the dll. Since it is being used you cannot remove it. You need to make sure that no process is using your dll before you can remove it. To achieve this you will need to find out which process is using it, why it is using it and make sure that it will be closed. If the problem occurs next time as well, then you will need to add closing that process to your script.
