How to Configure The refspec
In this post, we'll be using the jgit repository as our server repository, but we have to make a clone of it to a bare repository so we can push it. You can't push to the checked-out branch on a non-bare repository, as this can overwrite the work area and index.
Step 1 : Create a bare repository from the jgit repository and create a new Git repository
git clone --bare https://git.eclipse.org/r/jgit/jgit jgit-bare.git git init refspec-tests cd refspec-tests git remote add origin ../jgit-bare.git
Step 2 : We also need to change the branch names on some of the branches to match the example for namespacing;
for br in $(git branch -a | grep "stable-"); do new=$(echo $br| sed 's/-///'); git branch $new $br; done
Step 3 : Let's set up our new repository to only fetch the master branch. We do this by changing the fetch line under [remote "origin"] in the configuration file (.git/config), as follows:
[remote "origin"] url = ../jgit-bare.git fetch = +refs/heads/master:refs/remotes/origin/master
Step 4 : Now, we will only fetch the master branch and not all the other branches when executing a git fetch, git pull, or a git remote update origin, as follows:
git branch -a
Step 5 : Let's also set up a separate refspec to fetch all the stable* branches to the local repository as follows:
[remote "origin"] url = ../jgit-bare.git fetch = +refs/heads/master:refs/remotes/origin/master fetch = +refs/heads/stable*:refs/remotes/origin/stable*
Step 6 : Now, fetch the branches locally, as shown in the following command:
Step 7 : We can also set up a push refspec that specifies where branches are pushed to by default. Let's create a branch called develop and create one commit, as shown in the following commands:
git checkout -b develop echo "This is the developer setup, read carefully" > readme-dev.txt git add readme-dev.txt git commit -m "adds readme file for developers"
Step 8 : Now, let's create a push refspec that will send the content of the develop branch to integration/master on origin:
[remote "origin"] url = ../jgit-bare.git fetch = +refs/heads/master:refs/remotes/origin/master fetch = +refs/heads/stable*:refs/remotes/origin/stable* push = refs/heads/develop:refs/remotes/origin/integration/master
Step 9 : Let's push our commit on develop as follows:
As the integration/master branch didn't exist on the remote side, it was created for us.
