Summary

This document covers how to contribute to an Okta Open Source project. These instructions assume you have a GitHub.com account, so if you don't have one you will have to create one. Your proposed code changes will be published to your own fork of the Okta Java SDK project and you will submit a Pull Request for your changes to be added.

Lets get started!!!

Fork the code

In your browser, navigate to: https://github.com/okta/samples-java-spring-mvc

Fork the repository by clicking on the 'Fork' button on the top right hand side. The fork will happen and you will be taken to your own fork of the repository. Copy the Git repository URL by clicking on the clipboard next to the URL on the right hand side of the page under 'HTTPS clone URL'. You will paste this URL when doing the following git clone command.

On your computer, follow these steps to setup a local repository for working on the Okta Java SDK:

$ git clone https://github.com/YOUR_ACCOUNT/samples-java-spring-mvc.git
$ cd samples-java-spring-mvc
$ git remote add upstream https://github.com/okta/samples-java-spring-mvc.git
$ git checkout master
$ git fetch upstream
$ git rebase upstream/master

Making changes

It is important that you create a new branch to make changes on and that you do not change the master branch (other than to rebase in changes from upstream/master). In this example I will assume you will be making your changes to a branch called feature_x. This feature_x branch will be created on your local repository and will be pushed to your forked repository on GitHub. Once this branch is on your fork you will create a Pull Request for the changes to be added to the Okta Java SDK project.

It is best practice to create a new branch each time you want to contribute to the project and only track the changes for that pull request in this branch.

$ git checkout -b feature_x
   (make your changes)
$ git status
$ git add .
$ git commit -a -m "descriptive commit message for your changes"

The -b specifies that you want to create a new branch called feature_x. You only specify -b the first time you checkout because you are creating a new branch. Once the feature_x branch exists, you can later switch to it with only git checkout feature_x.

Rebase feature_x to include updates from upstream/master

It is important that you maintain an up-to-date master branch in your local repository. This is done by rebasing in the code changes from upstream/master (the official Okta Java SDK project repository) into your local repository. You will want to do this before you start working on a feature as well as right before you submit your changes as a pull request. I recommend you do this process periodically while you work to make sure you are working off the most recent project code.

This process will do the following:

  1. Checkout your local master branch
  2. Synchronize your local master branch with the upstream/master so you have all the latest changes from the project
  3. Rebase the latest project code into your feature_x branch so it is up-to-date with the upstream code
$ git checkout master
$ git fetch upstream
$ git rebase upstream/master
$ git checkout feature_x
$ git rebase master

Now your feature_x branch is up-to-date with all the code in upstream/master.

Make a GitHub Pull Request to contribute your changes

When you are happy with your changes and you are ready to contribute them, you will create a Pull Request on GitHub to do so. This is done by pushing your local changes to your forked repository (default remote name is origin) and then initiating a pull request on GitHub.

IMPORTANT: Make sure you have rebased your feature_x branch to include the latest code from upstream/master before you do this.

$ git push origin master
$ git push origin feature_x

Now that the feature_x branch has been pushed to your GitHub repository, you can initiate the pull request.

To initiate the pull request, do the following:

  1. In your browser, navigate to your forked repository: https://github.com/YOUR_ACCOUNT/samples-java-spring-mvc
  2. Click the new button called 'Compare & pull request' that showed up just above the main area in your forked repository
  3. Validate the pull request will be into the upstream master and will be from your feature_x branch
  4. Enter a detailed description of the work you have done and then click 'Send pull request'

If you are requested to make modifications to your proposed changes, make the changes locally on your feature_x branch, re-push the feature_x branch to your fork. The existing pull request should automatically pick up the change and update accordingly.

Cleaning up after a successful pull request

Once the feature_x branch has been committed into the upstream/master branch, your local feature_x branch and the origin/feature_x branch are no longer needed. If you want to make additional changes, restart the process with a new branch.

IMPORTANT: Make sure that your changes are in upstream/master before you delete your feature_x and origin/feature_x branches!

You can delete these deprecated branches with the following:

$ git checkout master
$ git branch -D feature_x
$ git push origin :feature_x
