title: Getting "error MSB3030: Could not copy the file" when no Copy is provided in project
body: <p>After migrating project from Visual Studio 2015 to Visual Studio 2015 I started to get the following error:</p>
  
  <p>C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(4358,5): error MSB3030: Could not copy the file "C:\p4client\ProAudio\dev_main_2018\ProAudio\XPlatform\AudioGrid\sdk\Project\Win\ag_sgring.pb.cc ag_sgring_pb2.py" because it was not found.</p>
  
  <p>However, in no place in project copy step was not specified.
  How can I find out what is asking this copy step and disable it?
  Was there any change between VS 2015 and VS 20017 in copy tasks?</p>
