Eclipse Plugin does not build for Hadoop 0.20.1

When trying to run the build script for the Eclipse Plugin in src/contrib/eclipse-plugin there are several errors a user receives. The first error is that the eclipse.home is not set. This is easily remedied by adding a value for eclipse.home in the build.properties file in the eclipse-plugin directory.

The script then states it cannot compile org.apache.hadoop.eclipse.launch.HadoopApplicationLaunchShortcut because it cannot resolve JavaApplicationLaunchShortcut on line 35:
import org.eclipse.jdt.internal.debug.ui.launcher.JavaApplicationLaunchShortcut;

and fails

I believe this is because there is no jar in the eclipse.home/plugins that has this class in that package. I did however find it in org.eclipse.jdt.debug.ui.launchConfigurations.JavaApplicationLaunchShortcut which was inside in org.eclipse.jdt.debug.ui_3.4.1.v20090811_r351.jar in the plugins dir of Eclipse 3.5

Changing the import in the class in the source to the latter allows the build to complete successfully. The M/R Perspective opens and works on my SLES 10 Linux environment but not on my Macbook Pro. Both are running Eclipse 3.5.

To users wanting to do the same, I built this inside Eclipse. To do that I added org.eclipse.jdt.debug.ui_3.4.1.v20090811_r351.jar and hadoop-0.20.1-core.jar to the ant runtime configuration classpath. I also had to set the version value=0.20.1 in the build.properties. You will also need to copy hadoop-0.20.1-core.jar to hadoop.home/build and commons-cli-1.2.jar to hadoop.home/build/ivy/lib/Hadoop/common.
