通过IDEA创建基于sbt的Scala项目，相关以来会通过sbt插件进行下载，由于是第一次创建，需要下载的jar包会比较多，时间会很长。
在等待sbt下载提示消失后，在控制台看到很多错误信息，主要错误内容如下：
Error:Error while importing SBT project:<br/>...<br/><pre>unresolved dependency: org.scala-sbt#process;0.13.7: not found unresolved dependency: org.scala-sbt#run;0.13.7: not found unresolved dependency: org.scala-sbt#relation;0.13.7: not found unresolved dependency: org.scala-sbt#task-system;0.13.7: not found unresolved dependency: org.scala-sbt#tasks;0.13.7: not found unresolved dependency: org.scala-sbt#tracking;0.13.7: not found
没有发现依赖包。
还有
connection refused之类的错误。应该是存储这个jar的仓库无法连接的问题。
解决方法：就是在sbt原有的repositories基础上(可以查看sbt-launch.jar文件)，创建一个新的repositories文件（位于用户的根目录下（/Users/admin/），创建.sbt目录，放在里面, 添加两个连接速度比较快的jar仓库即可，记得去掉每行尾部空白）

然后就会发现，依赖下载的速度快了很多。
