nexus 随笔

离线更新中央仓库索引的方式，速度快并且可靠。

1. 访问http://repo.maven.apache.org/maven2/.index/下载中心仓库最新版本的索引文件，我们需要下载如下两个文件nexus-maven-repository-index.gz和nexus-maven-repository-index.properties。
2. 进入nexus安装目录sonatype-work进入indexer目录，因为我们的代理名为central所以找到central-ctx ，将下载好的文件解压进去后。重新启动nexus，若能在central 的browse index中看到和remote一样的索引，即代表成功完成。

一些常用的软件仓库：

　　http://maven.aliyun.com/nexus/content/groups/public（阿里云，推荐）
　　http://repo1.maven.org/maven2
　　http://repository.sonatype.org/content/groups/public/

maven仓库位置寻找

　　http://mvnrepository.com

项目中直接使用其他仓库
