How to remove unused imports in Intellij IDEA on commit?

Is there a way to remove unused imports in Intellij IDEA on commit?

It is not very optimal to do it manually, CTRL + ALT + O helps but it's still manual.

If you are using IntelliJ IDEA or Android Studio:

Go to Settings > Editor > General >Auto Import and check the Optimize imports on the fly checkbox.

When you commit, tick the Optimize imports option on the right. This will become the default until you change it.

I prefer using the Reformat code option as well.

You can check checkbox in the commit dialog.

You can use settings to automatically optimize imports since 11.1 and above.

In Mac IntelliJ IDEA, the command is Cmd + Option + O

For some older versions it is apparently Ctrl + Option + O.

(Letter O not Zero 0) on the latest version 2019.x
