如何＆＃34;从标签中获取最新信息＆＃34;在PowerShell中使用Nant时？

Question

我正在编写PowerShell v5脚本来启动基于NAnt的自动构建过程。我还有一个用C＃编写的自定义任务（GetLatestFromLabel）。当我在DOS命令窗口中运行构建时，构建成功完成，但是当我从PowerShell v5脚本运行构建过程时，它似乎在将本地Windows文件路径添加到TFS源代码位置。

C:\Windows\sysWOW64\WindowsPowerShell\v1.0\$\AHLTAPrint\AWP 2.x.

以下是我遇到的错误：

SourceControl.GetLatestFromLabel:

     [echo] NewFolderVersion = 2.0.0.2

BUILD FAILED

INTERNAL ERROR

Microsoft.TeamFoundation.VersionControl.Client.ItemNotMappedException: There is no working folder mapping for C:\Windows\sysWOW64\WindowsPowerShell\v1.0\$\AHLTAPrint\AWP 2.x.
   at Microsoft.TeamFoundation.VersionControl.Client.Client.GetLocalWorkspace(String localPath, Boolean throwIfNotFound)
   at AHLTA.NAnt.TFS.Tasks.GetFromLabelTask.ExecuteTask() in c:\Workspaces\Ahltaprint\Build\NAnt.Extensions.Extended\AHLTA.NAnt.TFS.Tasks\Tasks\GetFromLabelTask.cs:line 66

   at NAnt.Core.Target.Execute()
   at NAnt.Core.Project.Execute(String targetName, Boolean forceDependencies)
   at NAnt.Core.Project.Execute()
   at NAnt.Core.Project.Run()

这是我的NAnt目标：

  <target name="SourceControl.GetLatestFromLabel">
    <property name="Private.SourceCodeFoldersfolders" value="$/AHLTAPrint/AWP 2.x" />
    <property name="Private.SourceCodeFoldersDelimiter" value="|" />

    <echo message="NewFolderVersion = ${NewFolderVersion}" />

    <tfsgetfromlabel tfsfolders ="${Private.SourceCodeFoldersfolders}"
                     labelname="${NewFolderVersion}"
                     folderdelimiter="${Private.SourceCodeFoldersDelimiter}">
      <connectioninformation refid="TFSConnection" />
    </tfsgetfromlabel>

  </target>

这是自定义任务的执行任务部分：

protected override void ExecuteTask()
{
    VersionControlServer vcs = base.TheConnectionInformation.GetVersionControlServer();
    if (vcs != null)
    {
        if (String.IsNullOrEmpty(TheFolderDelimiter))
        {
            /*** Only one folder ***/
            if (!String.IsNullOrEmpty(TheTFSFolders))
            {
                LabelVersionSpec version = new LabelVersionSpec(TheLabelName);
                Workspace ws = vcs.GetWorkspace(TheTFSFolders);
                if (ws != null)
                {
                    string[] items = { TheTFSFolders };
                    GetStatus gs = ws.Get(items, version, RecursionType.Full, GetOptions.Overwrite | GetOptions.GetAll);
                }
            }
        }
        else
        {
            // multiple folders in a string
            string[] folders = TheTFSFolders.Split(TheFolderDelimiter.ToCharArray());

            LabelVersionSpec version = new LabelVersionSpec(TheLabelName);
            for (int i = 0; i < folders.Length; ++i)
            {
                if (!String.IsNullOrEmpty(folders[i]))
                {
                    Workspace ws = vcs.GetWorkspace(folders[i]);
                    if (ws != null)
                    {
                        string[] items = { folders[i] };
                        Console.WriteLine("Getting Latest Code in " + items[0].ToString() + " From Label " + version.Label);
                        GetStatus gs = ws.Get(items, version, RecursionType.Full, GetOptions.Overwrite | GetOptions.GetAll);
                    }
                }
            }
        }
    }
}

知道发生了什么或我如何纠正这个问题？
