I have built the engine from source using 4.8 … and everything is working … but when I try to switch my game (previously from 4.7.6) to the new source build, I get the error below.


Running C:/Development/Epic Games/Source/UnrealEngine/Engine/Binaries/DotNET/UnrealBuildTool.exe  -projectfiles -project="C:/Development/Gobbo Games/Kaboom Arena/KaboomArena/KaboomArena.uproject" -game -engine -progress

UnrealBuildTool Exception: ERROR: UnrealBuildTool encountered an error while compiling source files

What the hell is BuildingRocket?

Does anyone have any ideas?

The game switched fine to 4.7 Binary release but I get the same error (as above) when I switch to the 4.8 Binary release. I am using the Right-Click -> Switch Unreal Engine Version.

Thanks

I had the same issue.

CodeSpartan’s answer to this question solved it for me.

In your case you’d look in KaboomArenaServer.Target.cs and change the BuildingRocket() call to IsEngineInstalled().

Hope that helps.
