1,、將hadoop解壓,。比如：D:\hadoop-1.0.3,。

2,、進入D:\hadoop-1.0.3\src\contrib目錄。將build-contrib.xml復(fù)制到D:\hadoop-1.0.3\src\contrib\eclipse-plugin目錄下,。

3、修改build-contrib.xml文件：

將hadoop.root改為hadoop解壓目錄,。

<property name=”hadoop.root” location=” D:\hadoop-1.0.3″/>

在下面添加如下兩行：Eclipse安裝根目錄，和hadoop版本,。

<property name=”eclipse.home” location=”D:\eclipse”/>

<property name=”version” value=”1.0.3″/>

4、在D:\hadoop-1.0.3\src\contrib\eclipse-plugin 目錄下創(chuàng)建lib目錄,，并將以下jar包復(fù)制進來：commons-configuration-1.6.jar,、commons-httpclient-3.0.1.jar,、commons-lang-2.4.jar

jackson-core-asl-1.8.8.jar、jackson-mapper-asl-1.8.8.jar.

5,、在D:\hadoop-1.0.3下創(chuàng)建build文件夾，將hadoop-core-1.0.3.jar復(fù)制進來,。

在D:\hadoop-1.0.3\build目錄下創(chuàng)建D:\hadoop-1.0.3\build\ivy\lib\Hadoop\common目錄并將commons-cli-1.2.jar復(fù)制到該目錄下。

6,、修改build.xml文件,。目錄：D:\hadoop-1.0.3\src\contrib\eclipse-plugin

<target name=”jar” depends=”compile” unless=”skip.contrib”>

<mkdir dir=”${build.dir}/lib”/>

<copy file=”${hadoop.root}/build/hadoop-core-${version}.jar” tofile=”${build.dir}/lib/hadoop-core.jar” verbose=”true”/>

<copy file=”${hadoop.root}/build/ivy/lib/Hadoop/common/commons-cli-${commons-cli.version}.jar” todir=”${build.dir}/lib” verbose=”true”/>

<copy file=”${hadoop.root}/build/commons-configuration-1.6.jar” todir=”${build.dir}/lib” verbose=”true”/>

<copy file=”${hadoop.root}/build/commons-httpclient-3.0.1.jar” todir=”${build.dir}/lib” verbose=”true”/>

<copy file=”${hadoop.root}/build/commons-lang-2.4.jar” todir=”${build.dir}/lib” verbose=”true”/>

<copy file=”${hadoop.root}/build/jackson-core-asl-1.8.8.jar” todir=”${build.dir}/lib” verbose=”true”/>

<copy file=”${hadoop.root}/build/jackson-mapper-asl-1.8.8.jar” todir=”${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>

7、修改：MANIFEST.MF文件。目錄：D:\hadoop-1.0.3\src\contrib\eclipse-plugin\META-INF

Bundle-ClassPath那一欄加入如下信息：

Bundle-ClassPath: classes/,

lib/hadoop-core.jar,

lib/commons-cli-1.2.jar,

lib/commons-configuration-1.6.jar,

lib/commons-httpclient-3.0.1.jar,

lib/commons-lang-2.4.jar,

lib/commons-jackson-core-asl-1.8.8.jar,

lib/commons-jackson-mapper-asl-1.8.8.jar

8、在控制臺切換到目錄D:\hadoop-1.0.3\src\contrib\eclipse-plugin,，使用Ant進行編譯（編譯過程中需要聯(lián)網(wǎng)，一些缺少的包會從網(wǎng)上下載）,。最后生成的結(jié)果會在D:\hadoop-1.0.3\build\contrib\eclipse-plugin下面。
