How to stop indexing the Maven "target" auto-generated folder?

Question

Is there a for Intellij to stop indexing auto-generated folder e.g. Maven target folder. It is very slow and hinders productivity when it starts indexing after building and running a project.

Specifically when I run mvn jetty:run it starts indexing when the target gets created with the compiled files. The indexing is painfully slow and happens every run which is causing developer time (a lot).

For a project with a huge code base, this indexing time is very slow.

Answer 1

You can Mark target folder as Excluded in the File | Project Structure | Modules | Sources tab.

Edit: also make sure it's not added as a library in the project.
