해결 

에러가 발생한 원인 

war을 packaging 하여 사용하는데 plugin에 추가하지 않았기 때문에 발생한 것이였다. 

 

pom.xml 상단에 서 <packaging>war<packaging>에서 war을 사용하지만, <plugin>으로 maven‑war‑plugin의 정확한 그룹ID/아티팩트ID/버전을 명시해 주지 않았기 때문에 Exception java.lang.ExceptionInInitializerError: Cannot access defaults field of Properties  에러가 발생 

 

해결 방법 :: 정확한 그룹ID/아티팩트ID/버전을 작성한다.
