Project causes UE source to rebuild...

Hi there,

I am currently trying to learn to work with the source build of UE 5.2

It works and I can create (some) projects. When I create a new project the editor closes after generating files. Then I do the following:

  • I go into the project folder and open the solution. Then trying to build the project completely rebuilds the inreal engine again. What is going on here? I get always this from the output:

1>[Upgrade] Using backward-compatible include order. The latest version of UE has changed the order of includes, which may require code changes. The current setting is:
1>[Upgrade] IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_1
1>[Upgrade] Suppress this message by setting ‘IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_2;’ in exampleproject2Editor.Target.cs.
1>[Upgrade] Alternatively you can set this to ‘EngineIncludeOrderVersion.Latest’ to always use the latest include order. This will potentially cause compile errors when integrating new versions of the engine.

What am I doing wrong? I look on random tutorials and there its done within a minute or so. Help is greatly appreciated.

I have the same bug. There is no solution given since 2014… I don’t know what to do…
