How to debug and fix build problems?

Hi, if you have full source code you can just debug UnrealBuildTool with the following command line (right click on UnrealBuildTool project → properties → Debug → Start Options) set in Visual Studio:

TargetName Platform Configuration

So assuming your game editor target name is MyGameEditor:

MyGameEditor Win64 Debug

Then just set UnrealBuildTool as your startup project in VS and Debug. All breakpoints set in you build.cs file should just work.
