The standard sbt eclipse plugin is not sufficient for maintaining the classpaths for eclipse projects.

A UpdateEclipseClasspaths tool exists to help with this. First you use sbt compile update-classifiers, then you run this tool (a scala app), and the classpaths of all daffodil sub-projects are updated to match those found by sbt including the source and javadoc links.

It needs refactoring to allow it to be used on more than just the daffodil project.
