小编给大家分享一下如何编译hadoop2.x的eclipse插件，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

注意：以下操作基于Hadoop-2.4.1，Eclipse Luna，Win7 64位

1、下载插件源码包

https://github.com/winghc/hadoop2x-eclipse-plugin

2、新建eclipse java工程，将压缩包中以下目录的内容复制到project中（只是放到eclipse里边看而已，并不使用eclipse编译）

5、在build.xml文件上Run AS Ant Build

Buildfile: D:\Lab\ws-hadoop-2\hadoop2x-eclipse-plugin\build.xml
init:
     [echo] contrib: eclipse-plugin
compile:
     [echo] contrib: eclipse-plugin
    [javac] Compiling 45 source files to D:\Lab\ws-hadoop-2\hadoop2x-eclipse-plugin\build\contrib\eclipse-plugin\classes
    [javac] 注: 某些输入文件使用或覆盖了已过时的 API。
    [javac] 注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。
    [javac] 注: 某些输入文件使用了未经检查或不安全的操作。
    [javac] 注: 有关详细信息, 请使用 -Xlint:unchecked 重新编译。
jar:
