Optimize imports on the fly not working

Question

I want imports to be deleted immediately after they become unused, so I checked Editor | General | Auto Import | Optimize imports on the fly, but it doesn't work.

Answer 1

If Optimize imports on the fly is selected as you have done, then unused imports should definitely be removed automatically, given that:

1. the file is recognized as a java file (it is located in a package under a Source Route.

and

2. the file is modified in some way (hit enter on a black line anywhere in the file, this will trigger imports optimization).

To optimize imports in many files at once, you can use ctrl+alt+O, or you can also tick Optimize Imports option when you check in files to source control (for example svn).

Answer 2

Please make sure that under Java | Imports, the Unused import (editor light) inspection is enabled.
