Clouding your Git Repo in Amazon S3 under Windows

Recently I tried to setup a Git repository in Amazon S3.
I found it pretty straightforward to do in Linux and Mac using JGit.
But I also needed to access my repo from a Windows box.
I googled a little bit, but most of the solutions where made using JungleDisk or Cloudberry.
I found an interesting link about JGit on Windows
"Using Git on Windows without any of the Cygwin/msysgit nonsense"
and I decided to try it in combination with Git and S3.

I tried just once, and it worked!

Here is the procedure I followed:

# Download and install "msysgit"
(currently Git-1.7.3.1-preview20101002.exe):
http://code.google.com/p/msysgit/

# Download and install "jgit.sh"
(currently org.eclipse.jgit.pgm-0.9.3.sh):
http://eclipse.org/jgit/download/

# Download and install Java (probably already installed):
http://www.java.com/en/download/index.jsp


# Rename "org.eclipse.jgit.pgm-0.9.3.sh" to "jgit" and put it in a directory "JGit"
# Create a batch file "jgit.bat" in the same directory with the following content:
java -cp jgit org.eclipse.jgit.pgm.Main %1 %2 %3 %4

# Add the path of the batch file to the environment variables so it can be found
in the command line ( System Properties -> Environment Variables).

# From the msysgit console test "jgit"
$ jgit version
jgit version 0.9.3

# Create a local git repository.
# In the Git console:

$ mkdir project
$ cd project
$ echo "initial test" > README
$ git init
$ git add .
$ git commit -m "initial commit"
$ git status

# Add your Amazon S3 keys accessible to "jgit":

$ touch ~/.jgit
$ notepad ~/.jgit
accesskey: xxx
secretkey: yyy

# Add the remote repository in the Amazon S3 bucket "yourbucket"
(previously created with some tool like S3Fox in Firefox)
$ git remote add s3 amazon-s3://.jgit@yourbucket/project.git

# Push your local repository to the bucket
$ jgit push s3 master

# To clone the repository you can do
$ jgit clone amazon-s3://.jgit@yourbucket/project.git

# To check
$ git remote -v

# If you want to keep consistency with the names:
$ git remote rename origin s3

# To commit your changes as usual:
$ git commit -a "updated repo"

# To push to your changes to your S3 bucket:
$ jgit push s3 master

# Because "jgit" doesn't have the pull command you have to split the steps:
$ jgit fetch s3
$ git merge s3/master

That's it. You can have access to your Git repo in Amazon S3 from a Windows box.

For Mac OS X and Linux you can check these blogs, from those I took some of the previous steps:
