丸趣 TV 小编给大家分享一下如何编译 hadoop1.x 的 eclipse 插件，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

注意：以下操作基于 Hadoop-1.2.1，Eclipse Luna，Win7 64 位

1、将 hadoop eclipse 插件的工程导入 Eclipse。插件源码目录如下：

D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\eclipse-plugin

2、配置工程依赖

3、准备 ant 的配置文件

D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\build-contrib.xml

将以上 build-contrib.xml 拷贝到项目目录中，并修改文件内容。具体如下：

  property name= name  value= ${ant.project.name} / 
  property name= root  value= ${basedir} / 
  property name= hadoop.root  location= D:/Lab/lib/hadoop/hadoop-1.2.1 / 
  property name= eclipse.home  location= D:/Program Files/Eclipse/eclipse-jee-luna-R-win32-x86_64 / 
  property name= version  value= 1.2.1 / 
  property name= build.contrib.dir  location= ${root}/build/contrib / 
  property name= build.dir  location= ${root}/build/contrib/${name} /

4、修改 build.xml

!-- 1. 修改  build-contrib.xml 的位置，去掉 ../  -- 
 import file= build-contrib.xml  / 
 !-- 2. 添加如下，否则提示 软件包  org.apache.hadoop.fs  不存在  -- 
 path id= hadoop-jars 
  fileset dir= ${hadoop.root}/ 
  include name= hadoop-*.jar  / 
  /fileset 
 /path 
 !-- Override classpath to include Eclipse SDK jars -- 
 path id= classpath 
  pathelement location= ${build.classes}  / 
  pathelement location= ${hadoop.root}/build/classes  / 
  path refid= eclipse-sdk-jars  / 
  path refid= hadoop-jars  / !-- 本行为添加内容 -- 
 /path 
 !-- 3. 修改并添加 jar 包, 有些包已经有了, 只添没有的  -- 
 !-- Override jar target to specify manifest -- 
 target name= jar  depends= compile  unless= skip.contrib 
  mkdir dir= ${build.dir}/lib  / 
  copy file= ${hadoop.root}/hadoop-core-${version}.jar  tofile= ${build.dir}/lib/hadoop-core.jar  verbose= true  / 
  copy file= ${hadoop.root}/lib/commons-cli-1.2.jar  todir= ${build.dir}/lib  verbose= true  / 
  copy file= ${hadoop.root}/lib/commons-lang-2.4.jar  todir= ${build.dir}/lib  verbose= true  / 
  copy file= ${hadoop.root}/lib/commons-configuration-1.6.jar  todir= ${build.dir}/lib  verbose= true  / 
  copy file= ${hadoop.root}/lib/commons-httpclient-3.0.1.jar  todir= ${build.dir}/lib  verbose= true  / 
  copy file= ${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar  todir= ${build.dir}/lib  verbose= true  / 
  copy file= ${hadoop.root}/lib/jackson-core-asl-1.8.8.jar  todir= ${build.dir}/lib  verbose= true  / 
  jar jarfile= ${build.dir}/hadoop-${name}-${version}.jar  manifest= ${root}/META-INF/MANIFEST.MF 
  fileset dir= ${build.dir}  includes= classes/ lib/  / 
  fileset dir= ${root}  includes= resources/ plugin.xml  / 
  /jar 
 /target

5、修改 MENIFEST.MF，在 Bundule-ClassPath 中增加一些依赖的 jar。

Bundle-ClassPath: classes/,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/hadoop-core-1.2.1.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-cli-1.2.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-configuration-1.6.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-httpclient-3.0.1.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-lang-2.4.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-core-asl-1.8.8.jar,
 D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-mapper-asl-1.8.8.jar

5、增加 Ant Builder。

6、编译

在 Project 菜单中 Build Project

7、运行结果
