Master Git in IntelliJ IDEA: A Step‑by‑Step Guide

Git Overview

Git is a widely used distributed version‑control system that maintains both a local repository and a remote repository. Most operations are performed locally, allowing you to commit and switch branches even without network connectivity. Git uses SHA‑1 hashes to ensure data integrity.

Configuring Git in IntelliJ IDEA

Install and Set Up SSH Key

Install Git on your machine and generate a suitable SSH key for authentication.

Configure Path to Git Executable

In IntelliJ IDEA go to File → Settings → Version Control → Git, set the Path to Git executable to the location of the Git binary, and click Test to verify the configuration.

Common Git Operations in IntelliJ IDEA

1. Clone a Repository

Navigate to VCS → Git → Clone.

Enter the remote repository URL and click Test to verify connectivity.

2. Checkout a Branch

Use the branch selector in the lower‑right corner of the IDE to choose the desired branch and click Checkout.

3. View Differences

In the Local Changes view, right‑click a file and select Show Diff to see modifications, or choose Revert to discard changes.

4. View Commit Log

Open Version Control → Log to browse the commit history.

5. Commit Changes

Modify files (e.g., pom.xml) which appear under Local Changes.

Click the upward‑arrow Commit button, write a commit message, and confirm.

6. Push to Remote

Select VCS → Git → Push to upload local commits to the remote repository.

Using Git from IntelliJ’s Built‑in Terminal

Press Alt+F12 (macOS) to open the terminal pane and run standard Git commands:

git clone <url>

git status

git checkout -b <branch> -t origin/<branch>

git pull

git commit -am "message"

git merge <branch>

git push

These commands provide the same functionality as the graphical actions described above.
