IntelliJ IDEA code reformat options

Question

When I press Ctrl + Alt + L , IDEA removes unused import. I want to turn this feature off, leave the unused imports there. Where can I affect this setting?

Answer 1

First check:

File | Settings | Editor | Formatting | Show " Reformat Code " dialog

Then when you hit Ctrl + Alt + L pop-up dialog will appear.

Uncheck Optimize imports and check Do not show this dialog in the future . Hit Enter or click Run . That's it!

Answer 2

In IDEA 2018, you can hit Ctrl + Alt + Shift + L and the reformat file pop-up will appear. Then you can check/uncheck the "Optimize Imports" option.
