The eclipse plug-in doesn't build using Hadoop 0.20.1 and Eclipse 3.5
(Galileo). I haven't tried to build it on 3.4, but the build errors
you're getting are the same as what you get for 3.5.
Even if you eliminate the compiler errors, the ant script doesn't
properly package the various plug-in resources. I'm not sure if the JIRA
listed below takes all this into account or not, as I haven't tried
their build, but I suspect it doesn't given your issues. You can,
however, easily fix and export the plug-in by importing the source into
your eclipse workspace, opening up any offending files, pressing
cmd+shift+o (which will import the correct packages -- the classes were
just moved, but the api is the same), and then going through the normal
PDE export process (which you should be able to find via Google).
The eclipse build issues (and maintaining the eclipse plugin) are
complicated by the fact that there's no unit tests for the plug-in, and
Eclipse doesn't publish up-to-date artifacts in any public maven or ant
repository, so its a pain to get Hudson, or whatever build server to
check it. I don't know weather or not this plug-in will ever be well
maintained unless a commercial vendor starts putting effort into it,
simply because Eclipse's APIs shift so frequently as to make maintaining
plug-ins for it quite prohibitive without some sort of commercial interest.

Hi, it's hadoop-0.20.1 and eclipse Ganymede. I did try that prebuilt plugin
over the weekend but no luck with that on Windows. Thank you.

You'll need to be more specific about
which version of Hadoop and Eclipse
you're using. There are known issues building the plugin on
Hadoop 0.20.1.
I am in the process of providing a patch for this, in the
interim, you
can try using the plugin jar attached at
http://issues.apache.org/jira/browse/HADOOP-6360
Kind regards
