title: Eclipse "Build Automatically" not cascading
body: <p>I have a project in Eclipse (Indigo but similar in Helios) which has files in <code>src/main/resources</code> which get processed to generate *.java source files in <code>target/generated-sources/xyz</code>. The project settings have "Build Automatically" enabled so whenever these resource files are edited and saved the corresponding <code>*.java</code> files are generated. I've added <code>target/generated-sources/xyz</code> to the projects Build Paths. This all works perfectly.</p>
  
  <p>The problem is that the changes to the generated <code>*.java</code> files are inconsistently rebuilt. If I have one of those files open in the editor, then it notices that it changed and asks if I want to reload it. Reloading the <code>*.java</code> files is enough for it to recognize that it has changed and trigger a rebuild. If I don't have it open then it doesn't automatically pick up the changes.</p>
  
  <p>Any ideas on what I can do to let Eclipse (Indigo preferably) know that these generated files are being updated? Or better yet tell it to monitor those folders directly?</p>
  
  <p>Thanks.</p>
