title: When does Eclipse copy resources to the output folder?
body: <p>I noticed that "sometimes" the resources i put into a source folder in my Eclipse project will not be copied to the output folder ("bin") immediately.<br>
  E.g. i change a properties file using the eclipse editor and save... and "bin" still has the old version.</p>
  
  <p>Does anyone know what exactly triggers the copying (and how i can trigger that from a plugin)?
  I thought it happened automatically when a resource changes.</p>
  
  <p>-- EDIT --</p>
  
  <p>To clarify what i meant by triggering it from a plugin: I have a plugin that depends on up to date resources in the output folder, but apparently the resources are outdated when my plugin is called. And that's why i need to better understand what happens and how i can force it when i need to.</p>
