Through this article, readers will learn how to efficiently manage version control of Java projects, avoid common problems, improve team collaboration efficiency, and master advanced Git skills to make Java development more efficient and amazing!

Branches allow you to experiment with code changes without affecting the main branch. Use <strong class="keylink">git</strong> checkout to create a new branch and use it when trying new features or fixing bugs. Once complete, use git merge to merge the changes back into the master branch.

Sample code:

git checkout -b new-feature
// 在 new-feature 分支上进行更改
git checkout main
git merge new-feature

2. Temporary work

Use git add to add the changes you want to track to the staging area. This allows you to selectively commit changes without committing all modifications.

Sample code:

git add MyFile.java

3. Submit and push

git commit Submit changes in the staging area to the local repository. Then, use git push to push the changes to the remote repository, making them accessible to other team members.

Sample code:

git commit -m "Fixed bug in MyFile"
git push

4. Code review

Git provides the ability to review code to improve code quality and collaboration. Use git request-pull to create a merge request so others can review your changes and provide feedback before merging.

Sample code:

git request-pull main new-feature

5. Conflict resolution

Merge conflicts may occur when multiple developers make changes to the same file at the same time. Use git mergetool to resolve conflicts, edit the files manually or use git checkout -ours or git checkout -theirs to select one side's changes.

Sample code:

git mergetool

6. Tags and versions

tag can create a specific version of the code snapshot. Use git tag to create a tag, then use git checkout to switch to that version.

Sample code:

git tag v1.0.0
git checkout v1.0.0

7. Remote tracking branch

Remote tracking branches are associated with branches in the remote repository. Use git remote add to add the remote repository to your local repository, then use git fetch to fetch its branch.

Sample code:

git remote add origin https://GitHub.com/my-org/my-repo.git
git fetch origin

8. Submodule

Submodules allow you to include external repositories into your project. Use git submodule add to add a submodule and git submodule update to update its contents.

Sample code:

git submodule add Https://github.com/my-org/my-submodule.git
git submodule update

9. Git Hooks

Git Hooks allow you to automatically execute custom scripts on specific events, such as commits or pulls. Set up the hook using git config and write the script using a scripting language such as Bash or python.

Sample code:

# pre-commit 钩子，在提交之前运行
git config core.hooksPath ~/.git-hooks
echo "#!/bin/bash" > ~/.git-hooks/pre-commit
echo "echo "You are about to commit"; exit 1" >> ~/.git-hooks/pre-commit
chmod +x ~/.git-hooks/pre-commit

10. Git Large File Storage (LFS)

LFS allows you to track and manage large files (such as images or multimedia files) without storing them in commit history. Use git lfs to install LFS, and use git lfs track *.png to track files.

Sample code:

git lfs install
git lfs track *.png

Summarize:

By mastering these Git secrets, Java developers can improve code management, collaboration, and quality. From branches and merges to tags and submodules, Git provides a comprehensive set of tools that enable teams to work efficiently and create more powerful applications.
