Eclipse target
When I checkout common, run ant eclipse and then open eclipse I get this error:

The type com.sun.javadoc.RootDoc cannot be resolved. It is indirectly
referenced from required .class
files ExcludePrivateAnnotationsJDiffDoclet.java /common/src/java/org/apache/hadoop/classification/tools line
1 Java Problem

The problem is that the tools.jar is missing during build.

Now I'm extremely novice when it come to the ant build.xml but I think
I solved the problem by ensuring the tools.jar is added to the eclipse
project files (i.e. the .classpath file).
My question to you all: is this the correct solution? Is it worth
submitting as a patch?
