Problems Building 'AutomationTool' in UE5

Tldr: Builds are failing in the AutomationTool when trying to Build the Server/Client because there seem to be files missing. I don't know how to fix that.

I'm currently trying to learn different things about UE5, following some Tutorials, and trying to grasp how servers and clients are done. On that note I was following https://docs.unrealengine.com/5.0/en-US/setting-up-dedicated-servers-in-unreal-engine/ . It uses the Lyra Game provided by them.

(1)Getting the Engine to run from source:

In order to Build the Server and Client they require the source version of UE, since Lyra uses 5.3 I got the 5.3 from their Github as described here https://docs.unrealengine.com/5.0/en-US/downloading-unreal-engine-source-code/ I'm using VS 2022 since I was already using it on my PC. I can open the engine and everything seems to work.

(2)Getting Lyra:

Done as in https://docs.unrealengine.com/5.0/en-US/lyra-sample-game-in-unreal-engine/ I can open Lyra and everything seems to work.

(3)Building the Client and Server:

When trying to build the server per the tutorial I was following originally, there are always 10 modules failing to build. With the following messages:

Metadata file 'H:\UnrealEngine-5.3\Engine\Binaries\DotNET\AutomationTool\AutomationScripts\Platforms\Android\ref\Android.Automation.dll' could not be found
Metadata file 'H:\UnrealEngine-5.3\Engine\Binaries\DotNET\AutomationTool\AutomationScripts\Scripts\ref\AutomationScripts.Automation.dll' could not be found

Metadata file 'H:\UnrealEngine-5.3\Engine\Binaries\DotNET\AutomationTool\AutomationScripts\Turnkey\ref\Turnkey.Automation.dll' could not be found
Metadata file 'H:\UnrealEngine-5.3\Engine\Binaries\DotNET\AutomationTool\AutomationScripts\Platforms\Windows\ref\Win.Automation.dll' could not be found

I found out that the Automation Tool seems to have been build incorrectly, since there are files missing. When looking over forum posts they suggested rebuilding the module. I did by right-clicking on the Automation Tool. (https://i.sstatic.net/ZN7SE.png) It cannot be Build correctly and many modules fail building for the exact same files are missing.

35>Done building project "AutomationTool.csproj" -- FAILED.
========== Rebuild All: 25 succeeded, 10 failed, 0 skipped ==========

What can I do?

After you clone/download UE source from Github, you need to run ./Setup.sh to download all of the dependencies. Epic hosts those outside of the Github repository but they are still required to build the engine successfully.

git clone https://github.com/EpicGames/UnrealEngine

cd UnrealEngine

./Setup.sh

./GenerateProjectFiles.sh

(On Windows, run Setup.bat and GenerateProjectFiles.bat instead).

After you complete these steps, Lyra should build successfully.

For more help with Lyra, see https://x157.github.io/UE5/LyraStarterGame

Check if there are any errors in C# part (Automotion, BuildGraph). I had two errors there that blocked Automotion compilation:

  • possible null on 'users' variable - I've added a null check to wrapping condition: if (reportNames != null && users != null)
  • parameter count mismatch - I've added missing {Arg} in the log line.

With those fixed I got whole solution successfully compiled.
