After converting to 4.16 I get UBT error : Failed to produce item

Converted from 4.15 to 4.16. The compile in VS2017 results in following error. How do I find log to get more info for below error?

ERROR : UBT error : Failed to produce item: C:\vso\msresearch\Theseus\AirSimEnvNH\Plugins\AirSim\Intermediate\Build\Win64\UE4Editor\DebugGame\UE4Editor-AirSim-Win64-DebugGame.lib

This seems to be the same issue as here.

TL;DR: While VS gives an error the code still compiles correctly (I can hear the hotloaded sound from the Editor, just check by putting some print statement in there and see if it appears despite what outcome VS states), so this is not a big issue. Current workarounds: Compile from inside the Editor or make a full Rebuild. But since there is no actual functionality issue I would just ignore the error and treat that as “one of those annoyances”. If the code actually does not compile, then this is another issue.
