“间歇”；已经添加了具有相同关键字的项目“；远程MSDeploy期间出错

在调用MSDeploy将Web包部署到远程计算机时，我们收到以下错误：

msdeploy.exe -source:package='G:'workspace'webPackage'WebPackage.zip' -dest:auto,computerName="HOST",includeAcls="False" -verb:sync -disableLink:AppPoolExtension -disableLink:ContentExtension -disableLink:CertificateExtension -setParamFile:"G:'workspace'webPackage'SetParameters.xml" 
Error: (12/10/2015 2:55:36 PM) An error occurred when the request was processed on the remote computer.
Error: An item with the same key has already been added.

这似乎发生在MSDeploy深处的某个地方。奇怪的是，这种情况并不总是发生；再次运行此命令似乎有效。有什么想法吗？
