> Eclipse Plugin does not build for Hadoop 0.20.1

>                 Key: HADOOP-6360
>                 URL: https://issues.apache.org/jira/browse/HADOOP-6360
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: contrib/eclipse-plugin
>    Affects Versions: 0.20.1
>         Environment: SLES 10, Mac OS/X 10.5.8
>            Reporter: Stephen Watt
>             Fix For: 0.20.1
>         Attachments: hadoop-0.20.1-eclipse-plugin.jar, HADOOP-6338.patch
> 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.
