.file->new -> project

2.选择Maven，添加模板创建项目

 3.填写Groupid、ArtifactId信息。GroupId：com.公司名称/个人名称.项目名；ArtifactId：子项目名称

4.选择本地安装的maven和setting.xml文件

5.工程名称和路径

 6.点击Finish. 修改pom.xml如下：

7.点击Import.导入jar包

8.如果无法创建scala文件. 则File->project Structure...Global Libraries 重新导下scala-sdk包即可(删除再添加，本人的环境可能有问题，正常不需要此操作)

9.com.rzx.ns目录下. 右键New->scala class 创建scala文件. 环境ok可以开发了。。。
