Failed to launch cm shell

voodooduck-jannick · June 6, 2025, 3:24pm

Jenkins setup:
Desktop Windows 10 Pro 10.0.19045, no docker or anything like that, just a Windows machine.
Jenkins Version 2.513
Jenkins logs in with the only user present which has admin privileges.
Unreal Engine Custom Source Build 5.4.4
Version Control: Unity Version Control

Hi!

We are using Jenkins to build and package our Unreal Engine game, although I think the core issue here does not have to do with UE but rather something Windows security/permissions related.

As of Windows update KB5051974 (release notes), we are getting the following error during the cooking command:

09:07:00 LogSourceControl: Error: RunCommand: ‘version’ TIMEOUT after 180.015s output (0 chars):
09:07:00 LogWindows: Warning: CreateProc failed: The filename, directory name, or volume label syntax is incorrect. (0x0000007b)
09:07:00 LogWindows: Warning: URL: cm shell --encoding=UTF-8 --enablestderr
09:07:00 LogSourceControl: Warning: Failed to launch ‘cm shell’

I used to be able to revert said windows update and the issue would be gone. However, it seems too much time has passed and so I cannot uninstall the update anymore.

This is the command I use to package the game:
"<UEBASEPATH>\Engine\Build\BatchFiles\RunUAT.bat" BuildCookRun -nop4 -project=<PROJECTPATH> -cook -stage -archive -archivedirectory=<ARCHIVEDIR> -package -clientconfig=Development -ueeexe=UEEditor-Cmd.exe -pak -prereqs -distribution -targetplatform=Win64 -build -utf8output

The <> have actual values in my command.
If I execute this command manually on the build machine, it works as intended.

I am desperate for help and would appreciate any input.

Thank you!

Do you execute the command as the same user that Jenkins is running as? Is the controller running ON Windows, or is this an agent? Can you output the environment for when you run it manually and also add a dump of the environment in your Jenkins?

Hi and thank you for your response!

Do you execute the command as the same user that Jenkins is running as?

As far as I know, yes. I am using the Execute Windows Batch File build step to execute it. This is all done in the Jenkins GUI, no custom scripts.

Is the controller running ON Windows, or is this an agent?

Unless I misunderstand, yes, the controller is running on Windows. Both Jenkins and the UE project are on the same machine.

Can you output the environment for when you run it manually and also add a dump of the environment in your Jenkins?

Don’t know if this is relevant
The path to the NintendoSDK is different.
For Jenkins it is
C:\Nintendo\NativeSDK16.2.3\NintendoSDK\Tools\CommandLineTools
And locally it is
C:\Nintendo\NativeSDK19.3.11\NintendoSDK\Tools\CommandLineTools
so a newer version.
If the cm exectuable that fails is from the SDK that might be the cause.

voodooduck-jannick · June 6, 2025, 6:54pm

I just changed it back to 16.2.3 so that is identical now and the error persists.
I am building for Windows right now so it shouldn’t matter anyway.

Thank you for your input though!

slide_o_mix · June 6, 2025, 7:31pm

My question about running the command manually is when you run the command manually on the command line, are you logging in as the same user as Jenkins is running as?

voodooduck-jannick · June 6, 2025, 8:26pm

Yes I am. There is only one user on that machine and the Jenkins service is configured to log on as that as well.

slide_o_mix · June 6, 2025, 9:00pm

The only remaining thing I can think of is that the cm shell requires interacting with the desktop somehow, which generally speaking Windows services are not allowed to do. There used to be a checkbox in the services “Log On” area but that is no longer the case.

There are a couple of options:

You can try bypassing this using this howto Q&A: Why doesn't "Allow service to interact with desktop" work? | The Core Technologies Blog
You could run an agent in a desktop session and then it wouldn’t be running under a service account when the job ran

I would recommend the second approach (though it comes with its own issues, such as starting the agent automatically, etc.).

voodooduck-jannick · June 11, 2025, 6:42pm

So after creating a second Windows admin user and changing Jenkins to log on with that user, after reconfiguring everything to build there, it worked once. Then, the error started occuring again. I finally found out about the -IgnoreCookErrors flag from UAT and started using it and it worked.

Now, after multiple successful builds, the error doesn’t even show up anymore for some reason. So I have removed that flag again.

I will keep monitoring it but if the error occurs again I will just use the -IgnoreCookErrors flag even though it isn’t a long-term solution.
