표준프레임워크는 maven으로
라이브러리가 관리가 되고 있습니다.

maven을 통한 jar 라이브러리 파일들이
알수 없는 이유로 제대로 내려오지 않은 문제가 발생할수가 있는데요.

pom.xml에 보면 전자정부 레포지토리는 다음을 추천드립니다.
<repository>
<id>egovframe</id>
http://maven.egovframe.kr:8080/maven/
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>

메이븐 레파지토리를 초기화할 필요도 있는데요.
프로젝트 우클릭 > Maven > Update Project를 선택하시고
Force Update ~~~에 체크후 OK선택하여
저장소를 초기화후에 재기동해 보시기 바랍니다.
