Resolving spurious project errors in Eclipse

Opening a workspace with several projects, I was presented with the following error for two of the projects:


The resolution was to force a resave of the selected projects (and their .classpath files):

Open the project properties

Select Java Build Path > Libraries

Add a new, arbitrary library (to be deleted later) > OK

Wait for the workspace to refresh (or force a refresh of the project)

The error(s) will go away

Remove the dummy library

The only other references I could find were to make minor alterations of contents of the .classpath file.
