function Remove-WhiskeyFileSystemItem { <# .SYNOPSIS Deletes a file or directory. .DESCRIPTION The `Remove-WhiskeyFileSystemItem` deletes files and directories. Directories are deleted recursively. On Windows, this function uses robocopy to delete directories, since it can handle files/directories whose paths are longer than the maximum 260 characters. If the file or directory doesn't exist, nothing happens. The path to delete should be absolute or relative to the current working directory. This function won't fail a build. If you want it to fail a build, pass the `-ErrorAction Stop` parameter. .EXAMPLE Remove-WhiskeyFileSystemItem -Path 'C:\some\file' Demonstrates how to delete a file. .EXAMPLE Remove-WhiskeyFilesystemItem -Path 'C:\project\node_modules' Demonstrates how to delete a directory. .EXAMPLE Remove-WhiskeyFileSystemItem -Path 'C:\project\node_modules' -ErrorAction Stop Demonstrates how to fail a build if the delete fails. #> [CmdletBinding()] param( [Parameter(Mandatory=$true)] [string] $Path ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState if( (Test-Path -Path $Path -PathType Leaf) ) { Remove-Item -Path $Path -Force } elseif( (Test-Path -Path $Path -PathType Container) ) { if( $IsWindows ) { $emptyDir = Join-Path -Path ([IO.Path]::GetTempPath()) -ChildPath ([IO.Path]::GetRandomFileName()) New-Item -Path $emptyDir -ItemType 'Directory' | Out-Null try { Invoke-WhiskeyRobocopy -Source $emptyDir -Destination $Path | Write-Verbose if( $LASTEXITCODE -ge 8 ) { Write-Error -Message ('Failed to remove directory "{0}".' -f $Path) return } Remove-Item -Path $Path -Recurse -Force } finally { Remove-Item -Path $emptyDir -Recurse -Force } } else { Remove-Item -Path $Path -Recurse -Force } } } |
