我使用的是hadoop-2.7.7，由于自学一切都的自己来，这次是编译一个eclipse 插件为hadoop测试用
编译环境：
JDK配置 ；
安装Eclipse （最新的eclipse 有一定问题 我这用的分享给大家链接：https://pan.baidu.com/s/128JqQc8nqRC1YI6hm6xk9A 密码：g51c ）
安装ant 参考：https://www.cnblogs.com/huangchanghuan/p/6597741.html 安装包（链接：https://pan.baidu.com/s/1XlGTl2tvzeSUI6wrt0ZsKw 密码：v0q4）
下载hadoop二进制包（hadoop-2.7.7.tar.gz）我这是用自己在win下编译的https://download.csdn.net/download/qq_32961893/10720328 官网下载的hadoop-2.7.7.tar.gz未测试
下载 hadoop2x-eclipse-plugin-master 官网地址：https://github.com/winghc/hadoop2x-eclipse-plugin
我用的版本链接：https://pan.baidu.com/s/10BUxbKW2WzM14PJlnc5FpQ 密码：sa71
编译：运行CMD，切换到XX\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin
也可以在XX\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin目录下按住shift+鼠标右键在此处打开命令窗口
执行编译，命令如下：
ant jar -Dversion=2.7.7 -Dhadoop.version=2.7.7 -Declipse.home=D:\eclipse -Dhadoop.home=E:\hadoop\hadoop-2.7.7
Dversion=Dhadoop.version --要编译的hadoop版本
Declipse.home=D:\eclipse eclipse所在位置
Dhadoop.home=E:\hadoop\hadoop-2.7.7 解压hadoop源码位置
执行等待一个漫长的过程
可能报错缺包体之类的
你可以看XX\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin下的build.xml文件配置
这些地方去E:\hadoop\hadoop-2.7.7\share\hadoop\common\lib中去找对应jar包修改build.xml配置我最重修改的build.xml
黏贴出来：`<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<include name="org.eclipse.team.cvs.ssh2*.jar"/>
<include name="com.jcraft.jsch*.jar"/>
</fileset>
<copy todir="${build.dir}/classes" verbose="true">

</fileset>

<jar
jarfile="${build.dir}/hadoop-${name}-${hadoop.version}.jar"
manifest="${root}/META-INF/MANIFEST.MF">
<manifest>
最后编译出来的结果在E:\hadoop\hadoop2x-eclipse-plugin-master\build\contrib\eclipse-plugin中，将hadoop-eclipse-plugin-2.7.7.jar拷贝到eclipse的D:\eclipse\plugins中即可使用
