Do I need to commit .gitignore?

Yes — .gitignore should be committed to the repository so all collaborators benefit from the same ignore rules.

How do I add custom patterns?

Open your .gitignore file and add the pattern on a new line. Use # for comments, * for wildcards, / to match directories, and ! to un-ignore a previously ignored path.

How do I ignore a file that is already tracked?

Adding a file to .gitignore does not remove it from tracking if it was previously committed. Run: git rm --cached to stop tracking it without deleting the file locally.

Why use Java + JetBrains together?

IntelliJ IDEA is the dominant Java IDE. The JetBrains template covers .idea/ workspace state, .iml module files, and out/ build directory. Combined with Java's .class files and archive artifacts, this gives comprehensive coverage for Java development in IntelliJ.
