title: eclipse mistakenly interprets packages as "resources", or source folders
body: <p>I'm importing an existing source tree as an Eclipse Java project. When I do, I get errors in classes (such as mycompany.logging.LogEntry) along the following lines:</p>
  
  <pre>The package mycompany.logging does not match the expected package ""</pre>
  
  <p>The problem seems to be that Eclipse does not realize that the directory src/mycompany/logging is a package directory --- instead it thinks it's a source folder in its own right, analogous to src/, and that LogEntry is part of the default package in that folder.</p>
  
  <p>Can anyone advise? Thanks very much.</p>
