What to gitignore from the .idea folder?

Question

Intellij Idea 9/10, what folders to check into (or not check into) source control?

I started using WebStorm for web development and am not sure what to add and what to exclude from our Git repository. Clearly some files inside the .idea folder are meant to be version controlled like the external library settings (jsLibraryMappings.xml) but others will probably change very often and are developer-specific (e.g., workspace.xml).

What is the recommended .gitignore pattern for WebStorm / IntelliJ IDEA?

P.S. There are already questions about this but usually focus only on whether to include the whole .idea folder or whether to fully exclude it. I think some of the files inside the .idea folder should be version controlled while others shouldn't and I'm trying to find out which ones.

Answer 1

The official support page should answer your question.

So in your .gitignore you might ignore the files ending with .iws, and the workspace.xml and tasks.xml files.

Answer 2

For a couple of years I was a supporter of using a specific .gitignore for IntelliJ with this suggested configuration.

Not anymore.

IntelliJ is updated quite frequently, internal config file specs change more often than I would like and JetBrains flagship excels at auto-configuring itself based on maven/gradle/etc build files.

So my suggestion would be to leave all editor config files out of project and have users configure editor to their liking. Things like code styling can and should be configured at build level; say using Google Code Style or CheckStyle directly on Maven/Gradle/sbt/etc.

This ensures consistency and leaves editor files out of source code that, in my personal opinion, is where they should be.

Answer 3

I just want to present a more recent alternative. There is an online tool that generates .gitignore files based on operating systems, IDEs and programming languages that you might be using.

gitignore.io
