I've created a new, currently empty Unity project (Unity version 2021.3.15f1) and have created a Github repository for it. I was having trouble with the initial commit--it kept throwing an error at me--so I tried following this guide https://unityatscale.com/unity-version-control-guide/how-to-setup-unity-project-on-github/ to see if I was doing anything specifically wrong. When I got to step 7/step 8, I got another error, so I decided to actually look through to see what was wrong. Almost every file threw up "LF will be replaced by CRLF the next time Git touches it", except for one:
error: open("ProjectName/Library/PackageCache/[email protected]/Runtime/VisualScripting.Core/Events/MessageListeners/MonoBehaviourMessageListeners/UnityOnControllerColliderHitMessageListener.cs.meta"): Filename too long error: unable to index file 'ProjectName/Library/PackageCache/[email protected]/Runtime/VisualScripting.Core/Events/MessageListeners/MonoBehaviourMessageListeners/UnityOnControllerColliderHitMessageListener.cs.meta' fatal: adding files failed
Once I unchecked that file from the commit, everything else committed just fine. This is the only file/change that won't commit. My question has a few parts.
- Do I need to commit this file?
- If I do need to commit this file, what happens if I don't?
- How do I fix this?
CodePudding user response：
No you should not commit this file. The whole Library folder isn't supposed to go into the repository, because it's generated by Unity.
What you need to do is:
Add a .gitignore file to your repository and commit it (as a single file). From then on git will ignore the Library folder and a lot of other things. It will keep working with git much cleaner.
There are templates specifically for Unity, like here: https://github.com/github/gitignore/blob/main/Unity.gitignore
How .gitignore works is explained here (https://git-scm.com/docs/gitignore).
