在~/.sbt/下添加一个repositories文件，里面内容如下：
PS：.sbt/文件一般在C:\Users\RYJ\ 下面，也可以使用类似Everything的工具快速搜索到。
[repositories] local aliyun: http://maven.aliyun.com/nexus/content/groups/public/ typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly sonatype-oss-releases maven-central sonatype-oss-snapshots
如果只是在单个项目中修改的话,在build.sbt里添加
resolvers += "aliyun" at "http://maven.aliyun.com/nexus/content/groups/public/"
