I have a project that uses some 3rd Party libraries. So the directory structure is something like:
MY_COOL_PROJECT
3rdParty
LIB_1
LIB_2
Source
MY_PROJECT
The libraries are located in separate repositories. So, if I want to use a git repository for the 3rd Party libraries I can do:
git subtree add --prefix 3rdParty/LIB_1 --squash http://My3rdPartyLibs.com/lib1.git master
However, inside lib1.git repository there is only one bin folder I need. It contains also folders such as documentation, examples, etc. How can I only "connect" my repository with lib1/bin folder instead of the whole repository? Is that even possible?

git subtree allows you to nest a repository as a subdirectory inside another. It's one of the various options for managing project dependencies in Git projects. You add a subtree to an existing repository where the subtree is a reference to another repository URL and branch/tag when you wish to utilize it.
Splitting the Original Repository The subtree commands effectively take a folder and split to another repository. Everything you want in the subtree repo will need to be in the same folder.
The –prefix parameter defines the root directory for the cloned repository, then add the remote url, the branch and let it squash the entire commit history (–squash). Git doesn't like uncommitted changes so make sure to stash/commit any existing changes before adding a new subtree.
Git submodules may look powerful or cool upfront, but for all the reasons above it is a bad idea to share code using submodules, especially when the code changes frequently. It will be much worse when you have more and more developers working on the same repos.
Normally, a git repo is done to be fully cloned/loaded.
You could go for a sparse checkout (Git1.7+), but only if you don't intent to do any modification and push those back. See this example:
$ git init
Initialized empty Git repository in /tmp/si-sandbox/.git/
(master) $ git config core.sparsecheckout true
(master) $ echo message-store/ >> .git/info/sparse-checkout
(master) $ git remote add origin git://github.com/iwein/Spring-Integration-Sandbox.git
(master) $ git pull origin master
The OP user2070238 reports:
This worked with a few changes.
Because, I use submodule I had to use
echo MY_FOLDER/* >> .git/info/modules/MY_MODULE/sparse-checkout
And for some reason the
MY_FOLDER/part was not working without*
