안녕하세요.
스프링부트2, 스프링 5로 공부중입니다.
강의에서 pom.xml에서 exclusions를 추가하여 log4j2로 변경하였는데 아래 처럼 에러가 나더라구요..
검색을 해보며 찾아보니
https://www.baeldung.com/slf4j-classpath-multiple-bindings
스프링에서 이런식으로 하라고 하는것 같은데 마찬가지더라구요..
왜 이런 에러가 발생하는걸까요??

아 깃주소를 올린다고 했는데 깜빡했네요..
말씀하신 mvn clean을 하여도 동일안 에러가 납니다.
아래는 pom.xml입니다

pom.xml 을 보여주시면 도움이 될거 같습니다. 일단은 아래 메시지만 보면 바인딩이 여러개여서 에러가 난걸로 보이네요. 즉, logback이 제대로 안빠진거 같은데요. mvn clean 을 한 다음에 다시 해보시죠.
