注意：以下操作基于Hadoop-1.2.1，Eclipse Luna

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=http://www.mamicode.com/"${ant.project.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
