[root@SudeepMangu apache-cassandra-1.2.5-src]# ant build build.xml run

你有网络问题。当http://repo2.maven.org在您的浏览器中运行时再试一次。

您可以在 Build.xml 中添加以下设置

**<setproxy proxyhost="**.**.**.**"
          proxyport="***"
          nonproxyhosts="*****.com"
          proxyuser="*****"
           proxypassword="****" />**
