Hello,
After a migration from UE4. I have a big issue. I have spend a lot of hours on it.
I use UE 5.6.1. I have try with a blanck test project and it works fine. So I think I have an error in my project.
I have compare the .cs and file in source folder between the two project and I see no difference. I have disable all plugin in the uasset file project (except one).
I have try all possibilities. Delete derivedcache/save/intermediate/.vs/bin/build folders.
Regenerate a sln file, build with vs20222. And try again to launch my project.
So the steps are after clean all and launch the project :
- I click YES to disable the plugin :
- I click yes to rebuild
The following modules are missing or built with a different engine version:
- I click OK on the error message
AgeOfAlbuvia could not be compiled. Try rebuilding from source manually.
- I right click on generate Visual Studio Project files
5. The file are correcly created.
- I Clic on Build solution in VS 2022 (developpment, Win64) :
Note I have two warnings at startup :
D:\DEV\Unreal Engine\Projects\AOA_UE5\depot_AOA\Intermediate\ProjectFiles\UE5.vcxproj : warning : The build tools for Visual Studio 2022 (v143) cannot be found. Install Visual Studio 2022 (v143) to build using the Visual Studio 2022 (v143) build tools.
D:\DEV\Unreal Engine\Projects\AOA_UE5\depot_AOA\Intermediate\ProjectFiles\UE5.vcxproj : warning : Platform ‘Win64’ referenced in the project file ‘UE5’ cannot be found.
Note I have errors : warning NU1902: Package ‘Magick.NET-Q16-HDRI-AnyCPU’ 14.7.0 has a known moderate severity vulnerability, https://github.com……
So I update the package, clean solution an rebuild solution again.
- After update the package, the build is correct :
========== Build: 51 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
- I start again my project with the same warning (I click yes before to disable the plugin) :
- I clic Yes but always the same error :
The following modules are missing or built with a different engine version:
AgeOfAlbuvia
Would you like to rebuild them now?
First Question, how it know there is a UE4 project ? Because the issue must be there.
Can someone have an idea to identify where the issue is located ?
More information for the manual command line build :
Note I have unistalled and make a fresh install of UE 5.6.1 Engine.
My source Files :
My AgeOfAlbuvia.Build.cs
// Fill out your copyright notice in the Description page of Project Settings.
using UnrealBuildTool;
public class AgeOfAlbuvia : ModuleRules
{
public AgeOfAlbuvia(ReadOnlyTargetRules Target) : base(Target)
{
PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });
PrivateDependencyModuleNames.AddRange(new string[] { });
}
}
My AgeOfAlbuviaTarget.cs (in UE4 it was AgeOfAlbuvia.Target.cs) :
// Fill out your copyright notice in the Description page of Project Settings.
using UnrealBuildTool;
using System.Collections.Generic;
public class AgeOfAlbuviaTarget : TargetRules
{
public AgeOfAlbuviaTarget(TargetInfo Target) : base(Target)
{
Type = TargetType.Game;
DefaultBuildSettings = BuildSettingsVersion.V5;
ExtraModuleNames.AddRange( new string[] { "AgeOfAlbuvia" } );
}
}
My AgeOfAlbuviaEditorTarget.cs (in UE4 it was AgeOfAlbuviaEditor.Target.cs) :
// Fill out your copyright notice in the Description page of Project Settings.
using UnrealBuildTool;
using System.Collections.Generic;
public class AgeOfAlbuviaEditorTarget : TargetRules
{
public AgeOfAlbuviaEditorTarget(TargetInfo Target) : base(Target)
{
Type = TargetType.Editor;
DefaultBuildSettings = BuildSettingsVersion.V5;
ExtraModuleNames.AddRange( new string[] { "AgeOfAlbuvia" } );
}
}
- If I try to build manually I have this error message :
D:\DEV\Unreal Engine\Projects\AOA_UE5\depot_AOA\Source\AgeOfAlbuvia\AgeOfAlbuvia.Build.cs(5,14): error CS0101: The namespace ‘’ already contains a definition for ‘AgeOfAlbuvia’

Location: D:\DEV\Unreal Engine\Engine\UE_5.6\Engine\Intermediate\Build\BuildRules\UE5Rules.dll
I see in logs :

And the dll files have 0 Ko :
