第一步：

新建一个普通的Maven项目

第二步：

右击项目 选择 config --> 选择 添加 scala环境，会自动在eclipse/plugins中下载两个文件

org.scala-lang.scala-library.source_2.11.8.v20160304

org.scala-lang.scala-reflect.source_2.11.8.v20160304

第三步：

修改pom.xml文件，导入Java和Scala 开发 Spark需要的jar包

（需要注意的是在第二步添加Scala环境的时候，默认Scala版本是2.11 所以添加Jar也要2.11的版本，否则会提示scala version problem 问题）
