'Remove middleman' IntelliJ refactoring on an empty interface

Question

I have an interface which is now empty, and extends another interface. I'd like to remove the empty interface and use the base interface, and am trying to find the correct refactoring in IntelliJ.

I've tried "remove middleman" but got "cannot perform the refactoring. The caret should be positioned at the name of the field to be refactored".

Answer 1

I think what you want to do is the "inline" refactor on the unwanted interface, e.g.

If

 
class Thing implements ThingA

and

interface ThingA extends ThingB

To get rid of ThingA

you do and inline (ctrl + alt + n) when the caret is on ThingA, you end up with:

class Thing implements ThingB
