Can't fetch private UPM Packages from github because can't add my github credentials to Unity

Bug description We’re using private packages from github in the Unity Package Manager. Building does not work with this because Unity asks for my github credentials. On my local Windows machine, Github Crendetial Manager pops up and I can insert them. What do I have to do in an github action to add them?

- stderr: fatal: could not read Username for 'https://github.com': terminal prompts disabled
Project has invalid dependencies:
de.lefx.stepmanager: Error when executing git command. fatal: could not read Username for 'https://github.com': terminal prompts disabled

I’ve tried to add my github credentials with fusion-engineering/setup-git-credentials@v2.0.1 but does not work either.

How to reproduce

Try building a project with UPM dependency from a private github URL.

Expected behavior

Project builds 😃

Additional details

I’ve added my script and the logfiles

build.zip logs_51.zip

That’s a fair point and thank you for elaborating on your use case, this is very helpful.

I suppose we could add gitUser and gitPassword as parameters and pass them into the image.

I believe unity has specific ENV variables it wants to use for UPM.

Open for contributions.

Since MYPACKAGE is a different repo i’m not sure this is going to work. In te last section of the page linked above https://docs.github.com/en/actions/security-guides/automatic-token-authentication#granting-additional-permissions it suggests that if you need more permissions that are given to the githubToken you would need to create a PAT (which would need to belong to a user).

I see. If that is GitHub official answer (for now) then so is ours. I stand corrected. Conceptually though not everyone has their own tokens for CI, just the person setting it up configures a token. Not sure if this is obvious for everyone or not.

As for the cases let’s also consider:

1. Packages from public repositories
2. A mixture, where some might be private or even vendor owned and others public or in the same repository.

That is to say that I think we’d like to support a similar solution as the one you proposed, as long as it works for everyone or is forward compatible with all cases in some way.

Finally, let’s see how much of the problem would get solved by https://github.com/game-ci/unity-builder/pull/278/files or how much of that PR can be reused.

Thank you for your extended explanation and consideration. 😃
