Spring Boot: Configuration Class 오류 해결 방법 - I/O Failure

클래스를 삭제하고 서버를 빌드할때 아래와 같은 에러가 발생하였습니다.

해당 에러는 삭제한 클래스를 찾아서 발생하는 에러 입니다.

gradle clean, invalidate caches를 해봐도 동일한 에러가 발생하였습니다.

그래서 클래스 파일이 생성되는 폴더(ex out폴더)에서 production 폴더를 삭제 후 다시 프로젝트를 빌드하니 production 폴더가 다시 생기고 삭제한 클래스가 다시 생기지 않아서 정상 빌드 되었습니다.
