maven nexus spring-data-jpa-examples导入报错

问题描述：
spring-data-jpa-examples一个基于maven的项目 ，我用nexus管理构件，但是项目导入myeclipse的时候会提示下面的错误

我的想法：
系统提示的意思就是"maven-plugin:1.0.0.RELEASE"这个构件不能从nexus上下载,
随后我在http://repo.springsource.org/ 上找到了该构件，我想问通过怎样的配置可以解决上面的问题，下面有我的maven配置和MyEclipse提示的错误

1.maven配置
setting.xml中关于nexus的配置

      </pluginRepositories>  
    </profile> 	
  </profiles>

2.MyEclipse提示的错误：
