Android SDK管理器显示更新项目时无法识别xcopy

每当我尝试使用以下命令更新我的项目：

android update project--path

，它都会显示下面给出的错误。 我的android sdk路径是：

S:\Androidapp\adt-bundle-windows-x86-20130514\sdk

我有我的java环境变量：java\u HOME:

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files (x86)\Java\jdk1.7.0_21\bin

命令提示时出错：

F:\tess-two-master\tess-two> S:\Androidapp\adt-bundle-windows-x86-20130514\sdk\tools\android update project -p F:\tess-two-master\tess-two.

我遇到了相同的问题。一时兴起，我只是从文件夹中复制了xcopy.exe并将其粘贴到android.bat所在的文件夹中，然后重新运行android.bat文件。瞧，它成功了

这不是一个优雅的解决方案，但像我这样的新手会在必要时使用蛮力；-）
