3. If it has error during compile. Here is a error that imported JavaApplicationLaunchShortcut class was not found. So, let fix the source code. Edit ${hodoop.home}/src/contrib/eclipse-plugin/src/java/org/apache/hadoop/eclipse/launch/HadoopApplicationLaunchShortcut.java.//Orginal
   //import org.eclipse.jdt.internal.debug.ui.launcher.JavaApplicationLaunchShortcut;
   //New
   import org.eclipse.jdt.debug.ui.launchConfigurations.JavaApplicationLaunchShortcut;
4. Then,
   $ ant package -Djava5.home="/path/to/java5/home" -Dforrest.home="/path/to/forrest/home"
5. You can see a generated hadoop-0.20.3-dev-eclipse-plugin.jar file in ${hadoop.home}/build/contrib/eclipse-plugin directory.
6. Copy it's to eclipse's plugins directory and start eclipse. You will see the plugin has been installed.
