Git support on Package Manager

Thank you but that's not my question.

I would to know what I need to do to import the external package of this project, because at this time if I just clone/download the project and import it in Unity there are some missing files...

 

Tell us exactly what you're doing and what the errors/missing files are.

As far as I know - assuming git is already installed on your system - it should be as simple as opening the downloaded project via the Unity Hub.

 

Is there any way to get the package manager to check for new versions of the git project. Allow you to update like with the Unity packages?

Lennart

 

Manually, you can. Just delete the lock that appears at the end of the packages file. They should include a section on the package manager that indicates if there's any update on that package and let the user update it.

 

Hey @okcompute_unity @maximeb_unity,

Thank you guys for your work and the communication here!

A question, if I may. Afaik, it was planned to add UI for Git dependencies in 2019.1, but in the manual it's now mentioned that installing a Git repo via Packages window is impossible. Does that mean you've decided to not add the UI for remote dependencies, or is it still in the works (what's the new ETA, in case it's the latter)?

 

@Elringus I think we don't rely on unity version to expect a feature anymore. The git support API will be added (or not) from the Package Manager package itself, not related to unity version. So they might still doing it, but the unity 2019 just already launched because it was not related and depend on each other anymore

 

I seem to run into a problem with git LFS on MacOSX...
On Windows everything goes fine but on Mac it can't seem to find git lfs even though when I run a terminal 'git lfs version' returns its version 2.7.2
I've installed git lfs via brew and initialized it, but still it won't budge. Anything I might've forgotten to config?

 

Hello, I've managed to make everything work as I wanted, but one thing remain on the git setup side of the thing.
When I look at, for example, Keijiro's repo (like this recent one https://github.com/keijiro/Rsvfx), he has (minimum) 2 branches, one with the full unity project, like master, and another one called upm which one has the necessary file for the package at the root. Does one of you know how to set up something like that with git ? Is it several .gitignore, or something like subtree or submodule (I'm not very knowledgeable about git)? Thanks !

 

I investigated complex ways to achieve this with git subtree and sparse checkouts and came to the conclusion it's better just to maintain the two branches manually. Git terrifies me once you get off the beaten track - it's ability to become a task in itself separately from the problem you're actually trying to solve is unparalleled outside of maybe the morbid allure of regular expressions.

 

@andybak Thank you, I absolutely agree with your statement regarding git, so I am going to do it manually as well !

 

Hi.
I've tried to add a git package, this one: https://github.com/kolodi/com.kolodi.unity-goodies
But I have errors.

When typing simply "https://github.com/kolodi/com.kolodi.unity-goodies" it says:

Cannot perform upm operation: Unable to add package ["https://github.com/kolodi/com.kolodi.unity-goodies"]: 

Package name '"https://github.com/kolodi/com.kolodi.unity-goodies"' is invalid. [InvalidParameter]

So I've tried "https://github.com/kolodi/com.kolodi.unity-goodies.git". It worked for some instants on and the I have the following error message:

Cannot perform upm operation: Unable to add package [https://github.com/kolodi/com.kolodi.unity-goodies.git]:

Error when executing git command. fatal: 'submodule' appears to be a git command, but we were not

able to execute it. Maybe git-submodule is broken? [NotFound]

Then I cloned the repo to my local machine and was able to add package from disk without any issue.

I'm using latest (at this moment) Unity: 2019.3.0a8

 

It likely is somewhere already answered but I was not able to quickly find this information:

• How to I provide all published versions via the package manager and not only the one specified via the git url/specific tag?
• Is it already possible to set up custom urls for the 3 links hardcoded (the last thing I have read somewhere was "plannet but not in yet - on the timeline for 2020")

 

As some people have said, The UI extension for git provided by this package is perfect!

This package seems to have been updated recently.
Try it!

@okcompute_unity @maximeb_unity,
Is there any plan for which these features is officially supported?

EDIT:
@Kichang-Kim @LennartJohansen @Elringus @misher,
Perhaps this plugin will solve your issues.

 

Issue resolved! You should add git bin folder path to the PATH variable on Windows. In my case it was: "C:\Program Files\Git\bin". Without it, "git submodule" command doesn't work.

 

This Patreon post explains how to do it:

Hi,
I can see the files in my custom package and seems to be imported correctly, but I can seem to access the classes?

Do you know what might be happening?

Im using this custom package to get started:
"com.namespace.unitypackageexample": "https://github.com/neogeek/unity-package-example.git#upm"

 

With a brief look it seems correct. Good minimal example. What error are you getting? Double-check the Library/PackageCache to see if it's the correct version.

 

The UPM still does not resolve the Git-LFS object through the hashed link. A temp solution is to not use LFS object in the custom-made package.

 

Thank you for your reply. I am going to try your described method on my Mac.

What's is a solution on Windows 10? I use both Mac and Windows regularly.

 

Just want to say thank you. Package Manager is pretty amazing.

+1 for GitHub subfolder, would be really useful.

 

Apologies if this has already been discussed, but I couldn't find anything on it. I've got a package with some code inside it that I'd like to move into a separate "sub" package. I put the code into a new repo and threw it up on github as a separate package. After that I added a dependency to the new package (via url to a specific commit) on the main package. When I added the main package to a test project via disk reference I got this error

Everything looks good to me so (assuming I didn't goof anything up) I was curious if packages support references to git urls. The reason I suspect I haven't messed anything up is b/c when adding the dependency to the main projects manifest, it was loaded correctly.

Package deps only support references by versions currently. The project manifest can state scoped registries to look them up in or directly add the package dep with git url needed for other referenced dep packages.

Hello.
I created my package.json and uploaded it on my gihub.
But I don't understand how to add this package to my project because in the package manager there is only a "Add Package From Disk". I can't choose to add a package from my github https://github.com/Thomas-6freedom/PirateToolChest

How to add a package in my project from my github ?

 

@Fangh add the url by hand into the manifest.json

 

https://docs.unity3d.com/Manual/upm-dependencies.html

That has the info on the supported ways to add a package to project manifest (as a dependency).

 

Try this: https://github.com/mob-sakai/GitDependencyResolverForUnity

 

Hey there,

I really enjoyed using packages until I got a problem with out of the blue, that git can't be found (on two different PCs), even though on both of them git is installed.

I tried opening the project with 2019.3.0f1, but it didn't work.
I also created a clean new project, but as soon as I add a simple dependency like upm-git-extension

"com.coffee.upm-git-extension": "https://github.com/mob-sakai/UpmGitExtension.git#1.0.1"

I get this:

About the Setup
Unity: 2019.3.0f1, 2019.2.10f1
UnityHub: 2.2.1
Windows: Windows10 Pro 1909

Git:

Code (cmd):

1. C:\>git --version
2. git version 2.24.0.windows.2
3. C:\>git-lfs --version
4. git-lfs/2.9.0 (GitHub; windows amd64; go 1.12.7; git 8ab05aa7)

Environment variables:
C:\Program Files\Git\cmd
C:\Program Files\Git\bin (Added afterwards since somebody mentioned it here)

As an obedient windows user I of course also tried restarting the computer.
I had no problems for the last 4 months using the package manager with custom packages, where do those problems come from? Anyone experiencing something similar and solved it? :S

 

Quick guess is environment variable

Most program normally find git with environment variable not by cmd

And it might need restart if env just changed

 

Thanks for the response. Yep, that would make sense, but I have set the environment variables and it worked without a problem for months.

Or did you set different variables? They are set as system variables (in PATH), not as user variables. Is that an issue?

 

I also only have `C:\Program Files\Git\cmd` in my system PATH variable

But maybe order matter. Might you try moving that path to the top or bottom and restart

 

Sadly that is not the problem. I did have "C:\Program Files\Git\cmd" as the only path as well and added the second path to try to fix the problem after it occured. Actually, on one machine I still just have the path "C:\Program Files\Git\cmd" as the only set path.

I tried a few more different approaches and found a strange solution: When starting the unity outside of the UnityHub, the package manager can access git and can pull the git repos. Strangly the package manager ui does not support selecting different versions in that case:


I also tried deleting the Hub (also with Revo Uninstaller), sadly without any luck. I opened a thread in the unity hub subforum: https://forum.unity.com/threads/unityhub-breaks-git-path-for-package-manager.788096/


TLDR: Open the project with the unity version directly instead of using the hub kind of works for me.

 

As of your describing I feel like current version of unityhub has a bug that overriding env variable and make a path variable missing from its env

 

The Unity Hub definitely messes with the env variables, since you need to restart it when you edit any of them (e.g. PATH). Restarting ONLY the Editor does not work, if the Hub is still running in the background.

 

Thanks for the info. I did try multiple times to kill the hub and restart my computer, I guess in my case there is a different cause.
Another thought I have: When I open the project directly through the editor exe while having the hub running as well, the git problem does not appear. And as I said, I have the problem on two different systems for newly created seperate projects.

 

What I mean is, the hub does not really change the system env directly, it could not

Bu every process that was opened could override its own env variable, like putting a stack on top of each other. And all the subprocess opened from it, and subprocess of the subprocess, will inherit those overridden env variable

 

I have the same issue than @Johannski and I described it here: https://forum.unity.com/threads/no-...system-and-restart-unity.730511/#post-5247206

Don't know why it doesn't work through the hub neither...

 

How did you solve this? I am also trying to call Rsvfx via manifest but the link seems incorrect.

 

To get a fancy UPM branch, you can follow this tutorial: https://www.patreon.com/posts/25070968


Now that I installed UnityHub 2.2.2 git is running again as it should, thanks for the fix!

I'm wondering however, the package manager window does not show any other versions for my projects, is this expected?

Cheers Johannes

 

Same problem here =(

 

Hello, this may have been already asked, but how can I manage a repository that has the package.json file not on the root folder?

 

There is a trick: https://github.com/starikcetin/awes...ME.md#how-to-support-upm-in-my-git-repository

To sum up: you create a separate branch with subtree split.

 

it worked, but it ignores the dependencies in the package file, is that normal?

 

At this page

https://docs.unity3d.com/Manual/upm-scoped.html

Attribute JSON Type Description
...
npm-compatible registry. For example, "url": "https://my.company.com/tools-registry"
...

the link points to a google doc that needs authentication to be seen

 

No, I have been using this method for a while and dependencies are working fine for me.

 

probably you declare 3rd party github dependencies as git URLS too , right?

 

Exactly

 

I didn't try, but as far as I understood :

However, UPM does not support git urls as dependencies in the package.

[ package-a/package.json ]
{
"name": "com.coffee.package-a",
"version": "0.1.0",
"dependencies": {
"com.coffee.core-a" : "https://github.com/mob-sakai/GitPackageTest#core-a-0.1.0"
}
}

this was not supported, is it now?
