In all of the `git submodule` or `git subtree` examples I can find, the submodule/subtree is referenced by a public, absolute URL.
We are using Bitbucket Server and accessing the repositories via HTTP. As such, the URL for a repository is different for each user. If I create a submodule using my personal URL, it will not be accessable to anybody else.
Is it possible for us to use `git submodule` or `git subtree` with Bitbucket Server?
