编译hadoop 1.0.1 eclipse plugin jar包

1、在Eclipse中选择File-->Import-->Existing Projects into Workspace导入已有项目，假设路径为：

/download/hadoop-1.0.1/src/contrib/eclipse-plugin，默认的项目名称是MapReduceTools

 

2、默认项目名称为MapReduceTools，然后在项目MapReduceTools中新建lib目录，并把hadoop的hadoop-core、commons-cli-1.2.jar、commons-lang-2.4.jar、commons-configuration-1.6.jar、jackson-mapper-asl-1.8.8.jar、jackson-core-asl-1.8.8.jar、commons-httpclient-3.0.1.jar拷贝到该目录。

 

3、修改../build-contrib.xml

 

  <property name="version" value="1.0.1"/>
  <property name="hadoop.root" location="/download/develop/hadoop-1.0.1"/>
  <property name="eclipse.home" location="/download/eclipse" />

 

4、修改build.xml

  <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="${hadoop.root}/lib/jackson-mapper-asl-1.8.8.jar"  todir="${build.dir}/lib" verbose="true"/>
    <copy file="${hadoop.root}/lib/jackson-core-asl-1.8.8.jar"  todir="${build.dir}/lib" verbose="true"/>
    <copy file="${hadoop.root}/lib/commons-httpclient-3.0.1.jar"  todir="${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、右键选择项目-->Export，类型选择JAR file，把plugin.xml文件、classes目录、lib目录和resources目录选上，选择导出的jar目录，即可导出hadoop-eclipse-plugin-1.0.0.jar文件

 

6、把该文件放到eclipse/plugin目录下面，重启eclipse
