这篇文章主要介绍“怎么搭建Spark源码阅读环境”，在日常操作中，相信很多人在怎么搭建Spark源码阅读环境问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”怎么搭建Spark源码阅读环境”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
1.安装JDK1.7、Maven3.2.5、Scala2.10.4
2.下载解压Spark1.4.0
下载地址：
3.下载安装 IntelliJ IDEA 14.1.4，给IDEA安装 Scala 插件，然后导入Spark项目
4.在IDEA中编译Spark
若编译时遇到如下图所示的错误：
在Maven视窗点击“Generate Sources and Update Folders For All Projects”，可解决此问题
在“Generate Sources and Update Folders For All Projects”过程中可能会遇到“Unable to import maven project: See logs for details”错误；可点击Help-->Show Log in Exploere，查看错误日志信息如下：
