Create Subtree

Add a new remote called plugin pointing to the plugin’s repository:

git remote add plugin https://path.to/remotes/plugin.git

Then Create a subtree specifying the new folder prefix plugins/demo. plugin is the remote name, and master refers to the master branch on the subtree’s repository:

git subtree add --prefix=plugins/demo plugin master

Pull Subtree Updates

Pull normal commits made in plugin:

git subtree pull --prefix=plugins/demo plugin master

Backport Subtree Updates

1. Specify commits made in superproject to be backported:

git commit -am "new changes to be backported"

1. Checkout new branch for merging, set to track subtree repository:

git checkout -b backport plugin/master

1. Cherry-pick backports:

git cherry-pick -x --strategy=subtree master

1. Push changes back to plugin source:

git push plugin backport:master
