Help to Build a Plugin for Unreal 5.3 and Unreal 5.4

[NISP2709]

When I am trying to open the project the Unreal Projects states that to build the plugin manually, So I am writing the command to build it for both the engine version. For the Both the Engine I getting different errors. This are the following commands and errors that I am getting while building the plugin:

I am not much of a programmer, Please guide if I am making some mistakes.

It has been mentioned in #1051 that the JSBSim plugin is compatible with UE 5.0-5.3. Note sure about 5.4. @gallonmate, any idea ?

@NISP2709, it is mentioned in the error report that you have posted that more details are available in logs:
UnrealBuildTool failed. See log for more details. (C:\Users\DigiCon\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_5.3\UBT-UnrealEditor-Win64-Development.txt)
and
UnrealBuildTool failed. See log for more details. (C:\Users\DigiCon\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_5.4\UBA-UnrealEditor-Win64-Development.txt)

Would you mind posting the content of these logs ?

[NISP2709]

Here are the log files for both the version that is generated.

Thanks.

Did you already follow all the steps in the Read Me file? https://github.com/JSBSim-Team/jsbsim/blob/master/UnrealEngine/README.md

Basically:
First open JSBSimForUnreal.sln and build it in Visual Studio.
Then you can right click on UnrealEngine\UEReferenceApp.uproject and select "Generate Visual Studio project files". After some time the file UEReferenceApp.sln will appear beside the uproject file. Open it and build it in Visual Studio. Try these steps with UE5.3 first.
