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-plugin2、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
/target5、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.jar5、增加 Ant Builder。
6、编译
在 Project 菜单中 Build Project
7、运行结果
