Git: Mastering Version Control

By: Aske Olsson, Jakub Narębski, Ferdinando Santacroce, Rasmus Voss

Overview of this book

Git is one of the most popular types of Distributed Version Control System. Since its inception, it has attracted skilled developers due to its robust, powerful, and reliable features. Like most powerful tools, Git can be hard to approach for the newcomers. However, this learning path will help you overcome this fear and become adept at all the basic and advanced tasks in Git. This course starts with an introduction to version control systems before you delve deeply into the essentials of Git. This serves as a primer for the topics to follow such as branching and merging, creating and managing a GitHub personal repository, and fork and pull requests. You'll also learn how to migrate from SVN using Git tools or TortoiseGit and migrate from other VCSs, concluding with a collection of resources, links, and appendices. As you progress on to the next module, you will learn how you can automate the usual Git processes by utilizing the hook system built into Git. It also covers advanced repository management, including different options to rewrite the history of a Git repository before you discover how you can work offline with Git, how to track what is going on behind the scenes, and how to use the stash for different purposes. Moving forward, you will gain deeper insights into Git's architecture, its underlying concepts, behavior, and best practices. It gives a quick implementation example of using Git for a collaborative development of a sample project to establish the foundation knowledge of Git operational tasks and concepts. By exploring advanced Git practices, you will attain a deeper understanding of Git’s behavior, allowing you to customize and extend existing recipes and write your own. This Learning Path is a blend of content, all packaged up keeping your journey in mind. It includes content from the following Packt products: • Git Essentials, Ferdinando Santacroce • Git Version Control Cookbook, Aske Olsson and Rasmus Voss • Mastering Git, Jakub Nar?bski

Using git rerere to merge known conflicts


While working on a feature branch, you probably like to merge daily or maybe more often, but often when you work on long-living feature branches, you end up in a situation where you have the same conflict occurring repeatedly.

Here, you can use git rerere which stands for reuse recorded resolution. Git rerere is not enabled by default but can be enabled with the following command:

$ git config rerere.enabled true

Tip

You can configure it globally by adding --global to the git config command.

How to do it…

Perform the following steps to merge the known conflicts:

  1. In the jgit repository folder, start by checking out a branch that tracks origin/stable-2.2:

    git checkout -b rerereExample --track origin/stable-2.2
    
  2. Now, change the maven-compiler-plugin version to something personalized such as 2.5.2 like this is in line 211. If you run git diff, you should get a result very similar to the following:

    $ git diff
    diff --git a/pom.xml b/pom.xml
    index 085e00f..d5aec17...
