안녕하세요 테스트 코드 진행중 가짜객체를 선언하기 위해 @mock를 사용하려는데 자바17과의 충돌?로 계속해서 에러가 발생하는 상황입니다..!

자바 버전 17에서 21로 변경, mockito 5.xx 최신 버전으로 변경해도 같은 에러에서 벗어나지못했습니다..
밑에는 전체 에러입니다.

ByteBuddy 버전도 올려서 빌드의존성 추가해봤는데도 안되네요

안녕하세요, 인프런 AI 인턴입니다.
오키님, 테스트 코드에서 @Mock를 사용할 때 발생하는 문제에 대해 말씀해주셨네요. 특히 자바 17과 관련된 문제로 보고 계신 것 같습니다.

주어진 에러 메시지를 기반으로 몇 가지 해결책을 제안 드립니다:

MockMaker 설정 확인: mockito-extensions 디렉토리 안에 org.mockito.plugins.MockMaker 파일이 존재하는지 확인해 주십시오. 이 파일의 내용은 “mock-maker-inline”이어야 합니다.

   mockito-extensions/
   └─ org.mockito.plugins.MockMaker (내용: mock-maker-inline)

ByteBuddy 버전 확인: 이미 ByteBuddy의 버전을 올려보신 것 같은데, 가급적 최신 버전을 사용하고 있는지 확인해 주세요.
JDK 버전 확인: 기본적으로 자바 17을 사용하고 계시지만, 빌드 환경이나 IDE에서 정확히 이 버전을 인식하고 있는지 확인해 주세요.
시스템 환경 변수 설정: Windows의 경우, Java 설치 폴더의 경로가 시스템 환경 변수에 올바르게 설정되어 있는지 확인해 주세요.
플러그인 버전 검토: org.springframework.boot과 io.spring.dependency-management 플러그인의 버전을 최신 자바 지원이 확인된 버전으로 업그레이드해보세요.
IntelliJ 등의 IDE 설정 점검: 테스트 실행 시 IDE 설정이 문제를 일으킬 수 있으니, IntelliJ 설정에서 JDK 버전이 정확히 설정되어 있는지 확인해 보세요.

위 방법을 통해 문제 해결에 도움이 되었으면 합니다. 추가적으로 다른 질문이 있다면 언제든지 문의해 주세요. 계속해서 학습을 이어가시길 바랍니다.
