Inspectopedia Help

Class extends annotation interface

Reports classes declared as an implementation or extension of an annotation interface.

While it is legal to extend an annotation interface, it is often done by accident, and the result can't be used as an annotation.

Locating this inspection

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
