스프링부트와 mockito 연동 문의

Question

안녕하세요 과정과 관련이 많진 않지만, 검색으로 해결책을 찾지 못해서 문의 드립니다ㅠ spring boot 2.4.13을 사용 중인데, mockito의 static mock을 사용하기 위해서 mockito-inline을 추가하면 잘 작동하던 @SpringBootTest에서 아래와 같은 오류가 발생합니다. gradle을 사용하고 , 아래와 같이 추가하였습니다. testImplementation 'org.mockito:mockito-inline:3.10.0' 아래는 에러 코드 입니다. java.util.ServiceConfigurationError: com.sun.tools.attach.spi.AttachProvider: Provider

안녕하세요.  eze 님, 공식 서포터즈 David입니다. jdk 버전을 업그레이드해주세요.   참고 It appears as if your JDK does not supply a working agent attachment mechanism. https://stackoverflow.com/a/68596428/10709777 감사합니다.
