Before you can start using Git, you need to generate an SSH key and add the public part of the key to your GitHub and Bitbucket accounts. That way, you can interact with private repositories without entering your username and password all the time. Just remember to clone the repository using the SSH clone URL.
As a part of git standardization we created this document which contains all the important information on how we are using git.
On most of the project we are going to use
master as main branch and
dev is not going to be used. All the development will be done on
master branch. Each release is tagged with the version number as it is described in Git standardization document.
We noticed that when having both
dev branches only one of them is used actively. Since we have tags on release commits, having a branch that only contains published code seems unnecessary. That is why, for the simplicity, we only keep the
master branch as the main branch and track releases via tags.
Before releasing the app on PlayStore, the release has to be tagged with the version number. Also, provide a short description for the release. Here's an example of adding a tag:
git tag -a v3.0.0 -m “The best version ever“ git push --tags
You can find more info about tagging here.
The development branch should always be named
master, for consistency across projects.
Branches are named according to their use, and words are delimited by dashes. You sould use Productive/Jira task number when possible. Some examples:
feature/123-login-screen enhancement/ui-improvements fix/533-pin-user-alert
Starting work on a new feature
git checkout master git checkout -b feature/123-login-screen
Merging the feature into
The preferred way of merging a branch back into
master is by creating a pull request and assigning it to a colleague for review.
There are two different roles in every pull request—the assignee and the reviewer. Reviewers are your colleagues who review your pull request, whereas the assignee is the person responsible for merging or cancelling the pull request—in other words, you.
If the branch cannot be merged back into
master because of a merge conflict, you need to fix the conflict on your feature branch by either rebasing from
git checkout feature/login-screen git rebase master
or by merging
master into your branch
git checkout feature/login-screen git merge master
Most projects have one active development stream at the moment. This means that all new changes should be included in the next upcoming release. Because of this, all changes can be merged into the
master branch without the need to introduce multiple
However, some projects have multiple releases planned ahead. It is possible that, at some point, a development team will work on multiple releases at the same time. In that case,
release branches should be introduced and handled in the same manner as the main
master branch. You can use regex to match all the release branches and not worry about protecting the newly created ones. Note: If you want to delete a protected branch on GitHub you will need to remove the protection because this can't be done, even with admin privileges.
When working with
release branches, it needs to be clear which task should be included in which version. If you are not sure, ask the project manager before starting the task. In Productive, release versions can be defined with tags or boards. In JIRA, you can track the status of each release and define a
Fix version/s attribute on a task.
After releasing a new version from the
release branch, make sure to create a new tag with that version from the last commit in that branch. Then you can merge the
release branch into the
master branch. Don't forget to also update all other active
Commit early, commit often
Don't forget to commit and push your code to the remote repository. This will protect you against losing your hard work. Make small commits with meaningful commit messages and push at least once a day.
Don't commit generated code
Generated code does not belong in the repo. Use the .gitginore file to exclude it. This file can be generated using the gitignore.io tool. All you need to do is write a few keywords (such as MacOS, Android, IntellJ, Android Studio), and the tool will generate the file content for you.
Don't commit chunks of commented out code
Don't comment out code and commit it to the repository so you can 'uncomment it if you ever need it again'. This creates a mess in the code and makes it less readable. It's easy to return to an earlier commit and look up the code that you removed, so there is no need to leave commented code lying around everywhere.
Resolving merge conflicts
Android Studio has a great built-in tool for resolving merge conflicts.
You can find it in
VCS Operations Popup.
Before you can use this tool, select Git as your VCS for your project under
You can find more details about the tool here.
For a quick overview of your commit messages for today and yesterday, you can use the following aliases:
alias today='git log --since=6am --format="* %s" --author="$(git config user.email)" --reverse -- | pbcopy' alias yesterday='git log --since=yesterday.6am --until=6am --format="* %s" --author="$(git config user.email)" --reverse -- | pbcopy'
