UE4 4.14 building for non editor builds fails with latest plugin from launcher. Any way to fix?

Question

After upgrading to Unreal 4.14, we ran into some issues when building the project for deployment. 

We were wondering if someone could shed some light on the situation.
This happens for any Non-Editor build configuration.
Debug, Development, or Shipping.
On local machines as well as a build server.

There are no warnings or errors thrown when building for editor configurations.

Thanks!

Answer 1

Do you by any chance use the new IO system that's experimental in UE 4.14? if USE_NEW_ASYNC_IO is defined somewhere in your engine code, FIOSystem doesn't exist, and it would lead to the errors you are seeing.

Are you compiling UE4 yourself?

I had build fails in unreal 4.14. Anyone know how to fix?
