Version Control History and Annotations - IntelliJ IDEA Tutorial

Welcome to the tutorial on version control history and annotations in IntelliJ IDEA. As you work on projects using version control systems like Git, it's essential to understand the history of changes and who made them. IntelliJ IDEA provides powerful tools to view the version control history and annotations, allowing you to explore the evolution of your code and understand its context. In this tutorial, you will learn how to view version control history, annotate code with commit details, and leverage these features effectively within IntelliJ IDEA.

1. Viewing Version Control History

IntelliJ IDEA allows you to view the history of changes made to your code. Here's how to access the version control history:

Step 1: Open the Version Control Tool Window

1. Open your project in IntelliJ IDEA.

2. Open the Version Control tool window by clicking on the corresponding icon in the toolbar.

Step 2: Explore the History

1. Switch to the Log tab in the Version Control tool window.

2. The history is displayed, showing the commits, commit messages, and other relevant information.

3. Click on a commit to see the details of that particular commit, such as the modified files and the changes made.

2. Annotating Code with Commit Details

Annotations provide a way to see who made changes to each line of code. Here's how to annotate code with commit details:

Step 1: Open a File

1. Open the file you want to annotate in IntelliJ IDEA.

Step 2: Enable Annotations

1. Open the Version Control tool window.

2. Switch to the Annotate tab.

3. The file will be annotated with colored markers representing the commits that modified each line of code.

4. Hover over the markers to see the commit details, such as the commit message, author, and timestamp.
