title: Eclipse project (or a Java package in a project) displays an error, yet none of the children have errors

  <p>In Eclipse, I have multiple places where this behavior occurs. As the sample above shows, a project can display an error, yet none of its children have an error. I cannot figure out where the error is that I need to fix. Also, as seen below, within a Java project, there can be an error on a package which, when expanded, has no errors among its children. </p>
