使用 nexus 的两大好处 (http://books.sonatype.com/nexus-book/reference/repoman-sect-repoman.html)：
Put simply, a repository manager provides two core features:
1. The ability to proxy a remote repository and cache artifacts saving both bandwidth and time required to retrieve a software artifact from a remote repository, and
2. The ability the host a repository providing an organization with a deployment target for software artifacts.

“Public Snapshot Repositories” 这个默认的 group 类型的 repository 在 nexus 1.6 中被移除，参见：

关于在使用 nexus 时 overridden 覆盖 super POM 中 id 为 central 的默认 repo：
即使你使用了 neuxs 作为 local repo manageer 并在其中 proxy 代理了 maven 中央仓库，但是 super POM 中 id 为 central 的 maven 中央仓库还是会在项目构建时起作用，造成的结果就是 nexus 两大好处中的第一条不起作用了！为了避免这个问题，可以借助 ～/.m2/settings.xml:
