使用ij写scala有两种方法，

1，使用maven来管理

创建maven项目后把java相关的路径删除，然后将java相关的路径都删除

在project structure将scala对应版本导入

2,使用sbt

在idea的sbt设置里面可以配Sbt的路径

并添加配置

-Dsbt.boot.directory=C:/Users/zhou1/.sbt/boot

-Dsbt.global.base=C:/Users/zhou1/.sbt

-Dsbt.ivy.home=C:/Users/zhou1/.ivy2

-Dsbt.repository.config=C:/sbt/conf/repo.properties

在.sbt/repo.properties里面可以自己指定源
