After cloning the source code and checking out the 4.27-plus branch, when I try to run the setup.bat file, I am encountering the following issue:

Iā€™m facing the same issue. Have you solved this?

I figured it out.
You need to replace this file in your engine directory:
UnrealEngine\Engine\Build\Commit.gitdeps.xml

With the latest one.
It exists as an asset file in the 4.27.2 release page:

https://github.com/EpicGames/UnrealEngine/releases/tag/4.27.2-release

This solution worked for me. Thanks, @DustyLane-DVG

Facing a new issue when running GenerateProjectFiles.bat.

The engine fails to compile because of Bink.

The first clue is when running GenerateProjectFiles.bat. You get this warning:

When running Setup.bat, it downloads the dependencies for Bink, but it places them in this folder:
Engine\Plugins\Media\BinkMedia\Source\
The problem is that it creates a new folder called SDK instead of using the BinkMediaPlayerSDK folder.

To fix compile issue:

  1. Run Setup.bat.
  2. Move the contents from inside Engine\Plugins\Media\BinkMedia\Source\SDK\ and place them inside Engine\Plugins\Media\BinkMedia\Source\BinkMediaPlayerSDK\.
  3. Delete the SDK\ folder.
  4. Run GenerateProjectFiles.bat.
  5. Compile engine.
