Master Git Basics: From Repository Creation to IDEA Integration

Git Overview

Key steps include creating a remote repository, cloning code, and using push/pull commands.

Create a remote repository on GitHub: log in, click the "+" button, choose New repository , fill in the name and options, then invite team members.

Clone the repository: copy the repository URL, open Git Bash in the desired local directory, and run:

git clone https://github.com/YourUser/Repo.git

Common remote and branch commands:

git clone <repo-url>               // clone remote repository
git remote -v                     // view remote aliases (default: origin)
git remote add <name> <url>       // add a remote alias
git branch -v                     // list branches
git branch <name>                 // create a branch
git checkout <name>               // switch to a branch
git push <remote> <branch>        // push to remote
git pull <remote> <branch>        // pull from remote

Typical workflow for committing changes:

git add <file>
git commit -m "message"
git push origin master
git pull origin master

Additional useful commands: git reflog , git log , git reset --hard <commit> , git merge <branch> , git rm --cached <file> , etc.

IDEA Integration

Configure IntelliJ IDEA to work with Git and perform repository operations directly from the IDE.

Set the Git executable path in IDEA settings.

Create a Git repository from within IDEA.

Clone, push, and pull repositories using IDEA's UI.

Add and commit files via the IDE.

Switch to a specific version (commit or tag) using the IDE's history view.

Create a new branch and switch to it directly from IDEA.
