windows下編譯hadoop-eclipse-plugin-1.1.2.jar插件

1、將hadoop-1.1.2.tar.gz解壓。比如：D:\hadoop-1.1.2。 

2、進入D:\hadoop-1.1.2\src\contrib目錄。將build-contrib.xml複製到D:\hadoop-1.1.2\src\contrib\eclipse-plugin目錄下。 
將 

<property name="name" value="${ant.project.name}"/>
<property name="root" value="${basedir}"/>
<property name="hadoop.root" location="${root}/../../../"/>

替換爲 

<property name="root" value="D:/hadoop-1.1.2/src/contrib/eclipse-plugin"/>
<property name="eclipse.home" location="D:/eclipse"/>
<property name="version" value="1.1.2"/>
<property name="hadoop.root" location="D:/hadoop-1.1.2"/>

3、修改 D:\hadoop-1.1.2\src\contrib\eclipse-plugin下的build.xml文件 

<pathelement location="${hadoop.root}/build/classes"/>

插入 

<pathelement location="${hadoop.root}/hadoop-core-1.1.2.jar"/>

把 

<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"/>

替換爲 

<copy file="${hadoop.root}/hadoop-core-${version}.jar" tofile="${build.dir}/lib/hadoop-core.jar" verbose="true"/>
<copy file="${hadoop.root}/lib/commons-cli-${commons-cli.version}.jar"  todir="${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="${hadoop.root}/lib/commons-lang-2.4.jar" todir="${build.dir}/lib" verbose="true"/>
<copy file="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>
<copy file="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar" todir="${build.dir}/lib" verbose="true"/>

4、修改：MANIFEST.MF文件。目錄：D:\hadoop-1.1.2\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/jackson-core-asl-1.8.8.jar,
 lib/jackson-mapper-asl-1.8.8.jar

5、在控制檯切換到目錄D:\hadoop-1.1.2\src\contrib\eclipse-plugin，使用Ant進行編譯。 

6、最後生成的結果會在D:\hadoop-1.1.2\build\contrib\eclipse-plugin下面。 

複製D:\hadoop-1.1.2\contrib\eclipse-plugin\hadoop-eclipse-plugin-1.1.2.jar 到 eclipse安裝目錄/plugins/ 下。
