由于1.0之后hadoop已经不自带eclipse的插件包了，所以得需要我们自己编译源码生成插件包。

hadoop的目录在/root/hadoop-1.2.0下面
eclipse的目录在/root/eclipse下面
总结一下如下的四步来完成编译eclipse插件的过程


步骤操作1进入/root/hadoop-1.2.0/src/contrib/eclipse-plugin下面，修改build.xml2进入/root/hadoop-1.2.0/src/contrib下面，修改build-contrib.xml3/root/hadoop-1.2.0/src/contrib/eclipse-plugin/META-INF下面，修改MANIFEST.MF文件4使用shell命令进入/root/hadoop-1.2.0/src/contrib/eclipse-plugin下面，执行ant命令进行构建

下面散仙就来详细介绍下，每一步具体怎么操作，在第一步里我们需要向build.xml里面，加入的内容有
1,eclipse的根目录.
2.hadoop的版本号.
3.hadoop的一些引用包.
4，在javac里加入  includeantruntime="on".
内容如下所示：


Xml代码  eclipse插件的编译——Hadoop1.2.0版_eclipse插件的编译——Hadoop

  1. <!-- 1,2步的配置  -->

  2. <propertyname="eclipse.home"location="/root/eclipse"/>

  3. <propertyname="version"value="1.2.0"/>

  4. <!--第3步的配置  -->

  5. <copyfile="${hadoop.root}/hadoop-core-${version}.jar"tofile="${build.dir}/lib/hadoop-core.jar"verbose="true"/>

  6. <copyfile="${hadoop.root}/lib/commons-cli-${commons-cli.version}.jar"tofile="${build.dir}/lib/commons-cli.jar"verbose="true"/>

  7. <copyfile="${hadoop.root}/lib/commons-configuration-1.6.jar"tofile="${build.dir}/lib/commons-configuration.jar"verbose="true"/>

  8. <copyfile="${hadoop.root}/lib/commons-httpclient-3.0.1.jar"tofile="${build.dir}/lib/commons-httpclient.jar"verbose="true"/>

  9. <copyfile="${hadoop.root}/lib/commons-lang-2.4.jar"tofile="${build.dir}/lib/commons-lang.jar"verbose="true"/>

  10. <copyfile="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar"tofile="${build.dir}/lib/jackson-core-asl.jar"verbose="true"/>

  11. <copyfile="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar"tofile="${build.dir}/lib/jackson-mapper-asl.jar"verbose="true"/>

  12. <!--第4步的配置  -->

  13. includeantruntime="on">


散仙会在下文贴出整个XML，现在我们看第二大步的配置，修改build-contrib.xml，内容如下：
Xml代码  eclipse插件的编译——Hadoop1.2.0版_eclipse插件的编译——Hadoop

  1. <!--  原始的为off -->

  2. lt;property name="javac.deprecation"value="on"/>


第三步的修改MANIFEST.MF内容如下：
Xml代码  eclipse插件的编译——Hadoop1.2.0版_eclipse插件的编译——Hadoop

  1. Bundle-ClassPath: classes/,lib/commons-cli.jar,lib/commons-httpclient.jar,lib/hadoop-core.jar,lib/jackson-mapper-asl.jar,lib/commons-configuration.jar,lib/commons-lang.jar,lib/jackson-core-asl.jar  



第四步执行命令：截图如下：

最后，插件类生成的目录，截图如下：


eclipse插件的编译——Hadoop1.2.0版_eclipse插件的编译——Hadoop_05

下面散仙给出所有配置的全部信息，以供参考，下图的是build.xml里面的内容

至此，已经ant编译完毕，截图如下

至此，插件已经完美生成，并运行，因为受上传限制的影响，所以散仙在这里上传不了这个jar包。
