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 b

Answer 1

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

Answer 2

In mac book

IntelliJ

Control + Option + o (not a zero, letter "o")

Answer 3

Or you can do the following shortcut :

MAC : Shift + Command + A (Enter Action menu pops up)

And write : Optimize Imports

Answer 4

Choose the project/module you want to remove unused import from in Project view. Then from Code menu choose Optimize imports and confirm with Run. The imports will be cleaned in whole project/module.

Answer 5

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 6

In IntelliJ, select the project you want to optimize imports on, go to Code menu and choose Optimize imports and a small Optimize Imports popup window will appear. On the popup window you need to click on Run button. Or alternatively, on IntelliJ on Mac, you can use a keyboard short cut Option + Command + O
