메이븐 셋팅하다보니 이런 에러가..

https로 땡겨오려다보니 이슈발생하는듯..

집에서는 잘 되는데 회사에서는 안되는게 많다. ㅠㅠ

{maven_home}/conf/setting.xml에 

    <mirror>

      <id>maven</id>

      <mirrorOf>central</mirrorOf>

      <name>repo</name>

      <url>http://repo.maven.apache.org/maven2</url>

    </mirror> 

<mirrors></mirrors> 사이에 추가해준다.

프로젝트 우클릭 - Maven - update project.. 클릭!

모두모두 잘된다 ㅠ_ㅠ
