一、准备工作：
Window7、JDK1.8、Eclipse、Hadoop-3.2.0安装包、eclipse-hadoop3x-master（https://github.com/Woooosz/eclipse-hadoop3x）、ANT（https://ant.apache.org/bindownload.cgi）
二、环境变量的配置
JDK1.8、ANT （安装目录的文件夹名称不能有空格，本人是在D盘新建Dev文件夹，将Eclipse、Hadoop-3.2.0、eclipse-hadoop3x-master、ANT都安装在此目录下）
三、配置build.xml文件：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

d: #进入D盘；
cd \Dev\eclipse-hadoop3x-master\src\contrib\eclipse-plugin
执行：ant jar -Dversion=3.2.0 -Dhadoop.version=3.2.0 -Declipse.home=D:\Dev\eclipse -Dhadoop.home=D:\Dev\hadoop-3.2.0
