IDEA配置Spark运行环境

在IDEA中添加scala插件 创建maven项目 并添加scala的sdk
前提 ：本地已安装Scala

1. 安装Scala插件(在线)

   Preferences -> Plugins -> Browse Repositories -> 搜索 scala -> install
   

2. 创建Maven工程

   File -> New -> Project… -> Maven -> Next
   

3. 引入Scala框架

   所在项目(点击右键) -> Add Framework Support… ->选择 Scala->点击 OK
   

相关依赖jar的引入 配置pom.xml

pom.xml
