sbt运行时经常需要下载大量的jar包，默认连接到maven官网，速度通常比较慢。
在`~/.sbt/`下添加一个`repositories`文件，里面内容如下：
[root@ooccpp scala]# cat ~/.sbt/repositories [repositories] local nexus-aliyun:http://maven.aliyun.com/nexus/content/groups/public nexus-aliyun-ivy:http://maven.aliyun.com/nexus/content/groups/public/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext] typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
