So what I’d recommend in the future for looking over logs is do perform a CTRL+F search for Error. Then you’ll see the errors that are stopping the project from successfully packaging. Warnings as you posted in your originally question can typically be ignored.
So here’s one that I see, as an example:
LogPackageName:Error: DoesPackageExist: DoesPackageExist FAILED: ‘/Game/BlueprintKeyRemapping/ExampleMap/FirstPersonExampleMap (2)’ is not a standard unreal filename or a long path name. Reason: Name may not contain the following characters:
This is an issue because your map name contains a space, which is not allowed for file names. Removing that space would resolve that particular error.
I also noticed a few errors seemingly related to p4, so I’d also recommend looking into those if the issue pops back up.
As far as the can’t find file warnings go, these can typically be ignored unless it’s a file that you know for sure that you are using. I’m not aware of a way to clean up the process that looks for the files, unfortunately.
Let me know if you have further questions, and I’m glad you were able to get the project to package successfully.
