Hadoop1.2.1-eclipse plug-in compilation

1. Install ant
# Sudo apt-get install ant
Ii. Modify the compilation configuration file
1. Find src/contrib/eclipse-plugin/build. xml in the hadoop installation directory and modify the following lines:

<path id="hadoop-core-jar">    <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-core-jar"/>  </path>

......

<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>

2. Locate the build-contrib.xml under/src/contrib/and add the following content:

<property name="version" value="1.2.1"/><property name="ivy.version" value="2.1.0"/><property name="eclipse.home" location="..."/>

Note: Replace the eclipse path with the eclipse storage path on your host.
3. Find the META-INF/MANIFEST. MF file under the src/contrib/eclipse-plugin directory to change the following:
Change Bundle-ClassPath: classes/, lib/hadoop-core.jar

Bundle-ClassPath: classes/,lib/hadoop-core.jar,lib/jackson-core-asl-1.8.8.jar ,lib/jackson-mapper-asl-1.8.8.jar, lib/commons-configuration-1.6.jar,lib/commons-lang-2.4.jar, lib/commons-httpclient-3.0.1.jar,lib/commons-cli-1.2.jar

4. Return src/contrib/eclipse-plugin Compilation
Ant
5. Find the compiled plug-in hadoop-eclipse-plugin-1.2.1.jar under {hadoophome}/build/contrib/eclipse-plugin and copy it to the plugin directory under eclipse {hadoophome} For hadoop installation directory)
Note: 1. installation in a network connection Environment
2. The compiled plug-in has nothing to do with the eclipse version. It only has something to do with the hadoop version and the eclipse installation directory.
