联通网络环境下无法访问http://repo1.maven.org/maven2/*库解决,镜像库添加
Maven 2的安装和使用虽然不是一点即用,但也不是很复杂。然而,这两天我新装Maven,刚刚过了mvn -version,尝试create maven project就出问题了。问题详情如下。发现联通宽带屏蔽了*库http://repo1.maven.org/maven2/  域名IP地址,搞不懂是怎么想的...电信可以正常访问。

开始以为是internet 代理设置有问题。网上也有帖子这么说。可是换到ADSL后,不用代理了,问题仍然存在。
几经周折后发现,原因在于自己的联通网络环境下无法访问*库,在网上找了几个镜像,其中有的镜像没有同步更新maven库。经过测试,如下maven 镜像工作正常:
  <mirrors>
    <mirror>
      <id>ibiblio.org</id>
      <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name >
      <url>http://mirrors.ibiblio.org/pub/mirrors/maven2</url>
      <mirrorOf>central</mirrorOf>
      <!-- United States, North Carolina -->
    </mirror>
   <mirror>
      <id>cica.es</id>
      <url>http://ftp.cica.es/mirrors/maven2</url>
      <mirrorOf>central</mirrorOf>
      <!-- Spain, Sevilla -->
    </mirror>
   
    <mirror>
      <id>skynet.be</id>
      <url>http://maven2.mirrors.skynet.be/pub/maven2</url>
      <mirrorOf>central</mirrorOf>
      <!-- Belgium -->
    </mirror>

  </mirrors>
在setting.xml中添加上面的镜像服务器
