Really useful to get all updates of remotes, or be sure to have commit or push all our work. However, it helps so much when dealing with multiple git repositories by assigning tags to them and perform git operations on selected (or all) git repositories in one command. Gr is a far less know project and does not provide the ability to include git repositories inside another one. The repo command is an executable Python script that you can put anywhere in your path. Repo is not meant to replace Git, only to make it easier to work with Git in the context of Android. Repo helps us manage the many Git repositories, does the uploads to our revision control system, and automates parts of the Android development workflow. Repo is a tool that we (Google) built on top of Git. Repo supports multithread git cloning, snapshots, shell operations on multiple repositories. It can be useful when dealing with very large set of git repositories, it uses a manifest XML file to describe the repositories to get and where to put them in the project tree. Repo is a tool written by Google on top of Git to help them manage the 17Gb of the Android source code in interaction with tehir continuous integration system. Gitslave's design is for simplicity for normal git operations. This sort of activity may be very familiar to CVS and (to a lesser extent) Subversion users. Similarly when you commit, push, pull, merge, tag, checkout, status, log, etc each git command will run on the superproject and all slave repositories in turn. Gitslave creates a group of related repositories-a superproject repository and a number of slave repositories-all of which are concurrently developed on and on which all git operations should normally operate so when you branch, each repository in the project is branched in turn. Git slave can be useful if your workflow need to perform same git operations on multiple project related repositories. A subtree is just a subdirectory that can beĬommitted to, branched, and merged along with your project in Repository to do anything special or to understand how subtrees Your repository, and do not force end-users of your gitmodule files or gitlinks) be present in Unlike submodules, subtrees do not need any specialĬonstructions (like. Subtrees are not to be confused with submodules, which are meant for Of the main project, optionally including the subproject'sįor example, you could include the source code for a library Subtrees allow subprojects to be included within a subdirectory However, it becomes much complex to use if a lot of code changes should be done and send in the included repositories. Git subtree has a much more simpler approach to include remote git repositories and has other advantages over submodules. With git subtree, the code and the history are merged in the top-level git repository. When cloning or pulling a repository containing submodules however, these will not be checked out by default the init and update subcommands will maintain submodules checked out and at appropriate revision in your working tree. This can be used to have external dependencies such as third party libraries for example. The other repository has its own history, which does not interfere with the history of the current repository. The use of submodule can become cumbersome when branching and some developers shared their tips or their hate working with submodules.Ī submodule allows you to keep another Git repository in a subdirectory of your repository. With git submodule, the code and the history remain in each repository. While the use of dependencies manager is really encouraged, because they do so much more than simply including remote repositories (minimum / maximum versions requirements, dependencies downloading, incompatibilities.), it exists several other solutions to include git repositories inside a main git repository.Įach solution may be adequate depending on the way you want to include and work with the remote sources: > git submodule
