저도 같은 문제를 겪었는데, pom.xml 파일에서 Wro4j 버전을 1.8.0으로 변경해서 해결했습니다.

Wro4jMojo has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0 저 플러그인이 자바 9 버전으로 컴파일 된 클래스 파일로 패키징 한 것 같은데, 자바 8로 실행하고 있어서 에러가 난걸로 보이네요. 자바 11 버전 설치하시고 다시 해보세요.
