当在TFS版本结束时运行时删除项错误

Question

我们有大量的构建经常发生大量源。因此，我们希望在每次构建之后构建源代码和分段目录。我正在使用内部版本的TFS 2015 Update 1中的vNext版本。我创建了一个PowerShell脚本作为执行删除最后一个任务：

[CmdletBinding()] 
param() 

begin { 
    function Delete-Directory { 
     param([string]$directory) 

     Write-Output "Attempting to delete '$($directory)'" 

     if (Test-Path $directory -pathType container) { 
      Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force 
      Write-Output "Successfully deleted the directory: '$($directory)'" 
     } else { 
      Write-Output "Failed to delete '$($directory)' as it does not exist" 
     } 
    } 
} 

process { 
    Delete-Directory $env:BUILD_SOURCESDIRECTORY 
    Delete-Directory $env:BUILD_STAGINGDIRECTORY 
} 
end{} 

本来，而是采用Get-ChildItem .... | Remove-Item，我用Remove-Item *path* -Recurse -Force但显然有一个与recurse parameter of Remove-Item一个问题。最初它有时工作。现在它从来没有工作。

我已经尝试了许多不同的变体，这里是一些结果：

随着-Recurse和-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force 

等于：

Get-ChildItem : Access to the path 'E:\GeneralAgent1\_work\3\s\TfsBuild' is 
denied. 
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:5 
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force 
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo : PermissionDenied: (E:\GeneralAgent1\_work\3\s\TfsBuild:String) [Get-ChildItem], Unauthor 
izedAccessException 
    + FullyQualifiedErrorId : DirUnauthorizedAccessError,Microsoft.PowerShell.Commands.GetChildItemCommand

没有-Recurse

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Force 

等于：

Remove-Item : Windows PowerShell is in NonInteractive mode. Read and Prompt 
functionality is not available. 
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54 
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Force 
+ ~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo : InvalidOperation: (:) [Remove-Item], PSInvalidOperationException 
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RemoveItemCommand

没有-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse 

返回大量错误的，1是权限被拒绝和其他人不能删除由于不被emtpy由于权限被拒绝之前：

Remove-Item : Cannot remove item 
E:\GeneralAgent1\_work\3\s\Proxies\Development\Isd.Proxies.BO_16.01.1\Avalara\StyleCop.Cache: 
You do not have sufficient access rights to perform this operation. 
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54 
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse 
+ ~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo : PermissionDenied: (StyleCop.Cache:FileInfo) [Remove-Item], IOException 
    + FullyQualifiedErrorId : RemoveFileSystemItemUnAuthorizedAccess,Microsoft.PowerShell.Commands.RemoveItemCommand 
...... 
Lots

没有-Recurse或-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item 

等于：

Remove-Item : Windows PowerShell is in NonInteractive mode. Read and Prompt 
functionality is not available. 
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54 
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item 
+ ~~~~~~~~~~~ 
    + CategoryInfo : InvalidOperation: (:) [Remove-Item], PSInvalidOperationException 
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RemoveItemCommand

我也尝试过其他组合并与Get-ChildItem参数出场，并得到了类似的结果。

构建代理帐户具有对根目录的完全权限。

请帮忙吗？

Answer 1

你应该可以，如果你从下往上去删除所有内容。排序中删除项目之前降序排列的Get-ChildItem结果通过其全名：

Get-ChildItem -Path $directory -Force -Recurse | 
    Sort-Object -Property FullName -Descending | 
    Remove-Item -Recurse -Force 

Answer 2

不知道这是你的修复，但我这样做只是有点不同

Get-ChildItem $FolderPath | ForEach-Object ($_){ 
    Remove-Item $_.FullName -Recurse -Force 
}
