maven利用nexus配置私服报如下异常如何解决？

先说下开发环境：

  1. apache-maven-3.1.1
  2. nexus-2.6.4-02-bundle

  3. jdk1.7.0_45

    最近开始使用maven构建项目（因为它实在太好用了），不过maven每次构建项目都要依赖中央仓库，这很不合理，所以使用了Nexus搭建了本地仓库，不过本地仓库搭建完成以后运行第一个命令mvn help:system就报了错，利用mvn -e help:system查看报错信息看了半天也没有头绪，下面就是这个报错信息：

我搜索了一部分报错信息，参考了Stack Overflow上的一些问题，猜测有可能是有些网站被墙所以无法下载一些.pom文件，不过当我将我的setting.xml中关于nexus的配置注释掉以后mvn help:system完全可以正常运行，所以应该是setting.xml的设置有问题：
