How to resolve 'detached HEAD' state when using Git with submodules?
I'm relatively new to this, so bear with me. I'm stuck on something that should probably be simple. Hey everyone, I'm running into an issue that's driving me crazy. I cloned a repository that uses submodules, but after checking out a specific commit, I found myself in a 'detached HEAD' state. I understand that this happens when you check out a commit instead of a branch, but I'm trying to work with both the main repository and its submodules effectively. Here’s a simplified version of what I did: ```bash # Cloning the repository with submodules git clone --recurse-submodules https://github.com/user/repo.git cd repo # Checking out a specific commit git checkout abc1234 # Now, entering the submodule directory git submodule update --init --recursive ``` After executing these commands, when I check the status, I see: ```bash HEAD detached at abc1234 ``` I need to make some changes in the submodule and push those changes back, but I’m unsure how to proceed without losing the state of the main repository. I’ve tried creating a new branch from the detached state: ```bash git checkout -b my-feature-branch ``` This seems to work for the main repository, but when I try to commit changes in the submodule, I get: ```bash fatal: You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, but you cannot commit the submodule. ``` I’m not sure how to manage the submodule while in this state. Should I checkout a branch in the submodule as well? I want to keep everything synchronized when I push my changes. Any advice on how to handle this situation without complicating my workflow would be greatly appreciated. This is part of a larger CLI tool I'm building. For reference, this is a production microservice. Thanks for your help in advance! What would be the recommended way to handle this?
