[JSON] 변환 오류...

Question

해당 string 파일을 jsonlint에서 돌려보고 문제가 없음을 확인한 후parser를 실행했는데 오류가 납니다. 왜그럴까요 ㅜㅜjava.lang.ClassNotFoundException: org.json.simple.parser.JSONParserat

JSONParser 클래스를 못찾는다고 하네요 컴파일 전에 빨간줄 뜰텐데.. 메이븐이든 그레이들 이든 그냥 라이브러리 쓰셧든 그쪽을 확인해보세요

org.json.simple 종속성이 maven 또는 gradle에 명시되어 설치했나요?혹은 해당 jar 파일이 있고, 올바르게 연동했나요? (lib 폴더 등)자바 9 이상, 11이나 17 쓰는 것 같은데, org.json.simple 패키지 버전이 너무 낮은 건 아닌가요?
