Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

    $ cd submodule
    $ git checkout v2.0
    Previous HEAD position was 5c1277e... bumped version to 2.0.5
    HEAD is now at f0a0036... version 2.0

`git-status` on the parent repository will now report a dirty tree:  

    # On branch dev [...]
    #
    #	modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

&gt; Step 1: Add the submodule
&gt; 
&gt;        git submodule add git://some_repository.git some_repository
&gt; 
&gt; Step 2: Fix the submodule to a particular commit
&gt; 
&gt; By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.
&gt; 
&gt;        git checkout -b some_branch origin/some_branch
&gt; 
&gt; Now the submodule is fixed on the development branch instead of HEAD of master.

I am working with an open source project that is built with Gradle. I would like to generate a *(project)-sources.jar* file that I can load into my IDE (IntelliJ IDEA) and debug through the project. I know how to load the file if I can generate it.

I have looked through the available Gradle tasks for the project and there isn&#39;t one that generates a sources jar file.

What is the easiest way to generate a sources jar file for this project?

Adding the source into the jar file that contains the compiled class files would be fine as well.

    ids.add(&quot;4&quot;);

Now i want an output from this list as 1,2,3,4 without **explicitly** iterating over it.

I have two branches with the exact same file (incase you are wondering it is a .sql file) and I want to interactively merge it.

Pretty much I want to open up a diff program like I do when there is a conflict (or command line) and select exactly what lines go where.

Is there anyway to do this?

while installing smartgit 3.0.4 I checked the commercial licensing option, because I was just clicking &quot;next&quot; button : ) (30 day trial and then you have to buy it). Now today is my 31st day of using SG and I can&#39;t change my licensing options (reinstalling smartgit doesn&#39;t help) and I&#39;m not able to use SG anymore without paying (I&#39;m not using it for commercial purposes). Do you know how to fix it?

I have one repo hosted at https://github.com/aikiframework/json . On my local copy, I added a submodule using the command

    git submodule add git@github.com:jcubic/json-rpc.git json-rpc

Then I did a commit and push, and the changes appear on GitHub (I can click on it). But when I clone the repo

    git clone https://github.com/aikiframework/json.git

the submodule folder json-rpc is empty.

What am I missing here? Did I forget about something? Why is that folder empty?

Empty Git submodule folder when repo cloned

Is there a flag to pass to `git` when doing a clone, say don&#39;t clone the `.git` directory? If not, how about a flag to delete the `.git` directory after the clone?

Git clone without .git directory

I used to work under Subversion/SVN and was instantly using nice feature called keyword substitution. Just putting in source files smth like:

    /*
     *   $Author: ivanovpv $
     *   $Rev: 42 $
     *   $LastChangedDate: 2012-05-25 21:47:42 +0200 (Fri, 25 May 2012) $
     */

And each time Subversion was substituting keywords (Author, Rev, LastChangedDate) with actual ones.

Some time ago I was forced to move to Git and just wondering is there&#39;s something similar to Subversion&#39;s keyword substitution in Git?

Git keyword substitution like those in Subversion?

I have a folder, which was a git repo. It contains some files and .gitmodules file. Now, when I do `git init` and then `git submodule init`, the latter command output is nothing. How can I help git to see submodules, defined in .gitmodules file without running `git submodule add` by hand again?

Update:
this is my .gitmodules file:

    [submodule &quot;vim-pathogen&quot;]
    	path = vim-pathogen
    	url = git://github.com/tpope/vim-pathogen.git
    [submodule &quot;bundle/python-mode&quot;]
    	path = bundle/python-mode
    	url = git://github.com/klen/python-mode.git
    [submodule &quot;bundle/vim-fugitive&quot;]
    	path = bundle/vim-fugitive
    	url = git://github.com/tpope/vim-fugitive.git
    [submodule &quot;bundle/ctrlp.vim&quot;]
    	path = bundle/ctrlp.vim
    	url = git://github.com/kien/ctrlp.vim.git
    [submodule &quot;bundle/vim-tomorrow-theme&quot;]
    	path = bundle/vim-tomorrow-theme
    	url = git://github.com/chriskempson/vim-tomorrow-theme.git
and here is listing of this dir:

    drwxr-xr-x  4 evgeniuz 100 4096 июня  29 12:06 .
    drwx------ 60 evgeniuz 100 4096 июня  29 11:43 ..
    drwxr-xr-x  2 evgeniuz 100 4096 июня  29 10:03 autoload
    drwxr-xr-x  7 evgeniuz 100 4096 июня  29 12:13 .git
    -rw-r--r--  1 evgeniuz 100  542 июня  29 11:45 .gitmodules
    -rw-r--r--  1 evgeniuz 100  243 июня  29 11:18 .vimrc
so, definitely, it is in top level. the git directory is not changed, only `git init` is done

Restore git submodules from .gitmodules

I am attempting to add a few submodules to my `.vim/bundles` directory, and when I attempt to add this particular repo Git gives me a strange error I&#39;ve never seen before:

    $ git submodule add -f git://github.com/derekwyatt/vim-scala.git .vim/bundle/vim-scala
    fatal: You are on a branch yet to be born
    Unable to checkout submodule &#39;.vim/bundle/vim-scala&#39;

Any idea what can cause this?

If I clone the same repo to a test directory (not through the submodule command), it works fine, and creates the expected files.

&quot;You are on a branch yet to be born&quot; when adding git submodule

Quite often it is the case that you&#39;re writing a project of some kind, and after a while it becomes clear that some component of the project is actually useful as a standalone component (a library, perhaps). If you&#39;ve had that idea from early on, then there&#39;s a fair chance that most of that code is in its own folder.

Is there a way to convert one of the sub directories in a Git project to a submodule?

Ideally this would happen such that all of the code in that directory is removed from the parent project, and the submodule project is added in its place, with all the appropriate history, and such that all the parent project commits point to the correct submodule commits.


Convert a Git folder to a submodule retrospectively?

I have a Git repository that has several submodules in it. How do I list the names of all the submodules after `git submodule init` has been run?

The `git submodule foreach` command could echo the names of the submodule, but that only works once they have been checked out which has not happened after the init step. There are more steps in the chain that need to happen before they can be checked out, and I don&#39;t want to have to hard-wire names of submodules into the script. 

So is there a Git command to get the names of all currently registered, but not yet checked out submodules?
