如何編譯hadoop2.x的eclipse插件

小編給大家分享一下如何編譯hadoop2.x的eclipse插件，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

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

1、下載插件源碼包

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

2、新建eclipse java工程，將壓縮包中以下目錄的內容復制到project中（只是放到eclipse里邊看而已，并不使用eclipse編譯）

hadoop2x-eclipse-plugin-master.zip\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin

3、修改build.xml如下

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

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: 某些輸入文件使用或覆蓋了已過時的 API。
    [javac] 注: 有關詳細信息, 請使用 -Xlint:deprecation 重新編譯。
    [javac] 注: 某些輸入文件使用了未經檢查或不安全的操作。
    [javac] 注: 有關詳細信息, 請使用 -Xlint:unchecked 重新編譯。
jar:
      [jar] Building jar: D:\Lab\ws-hadoop-2\hadoop2x-eclipse-plugin\build\contrib\eclipse-plugin\hadoop-2.4.1-eclipse-4.4-plugin.jar
BUILD SUCCESSFUL
