How to remove unused imports in Intellij IDEA on commit?

Question

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.

Answer 1

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.

Answer 2

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.

Answer 3

You can check checkbox in the commit dialog.

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