Executing eclipse plugin automatically

Question

I try to create an eclipse plugin which deletes some files when eclipse workbench is closed. I started with the Hello, World command plugin project and added a IWorkbenchListener like mentioned in this toppic Eclipse shut down hook able to stop the termination. The listener is added when I press a special button in the eclipse menu bar (which is added by this plugin).

How can I automatically add this IWorkbenchListener, without the need of clicking on any menu entry?

Use the org.eclipse.ui.startup extension point to specify a class that implements org.eclipse.ui.IStartup. This will be called early on during Eclipse initialization.

So in the plugin.xml:

<extension
 point="org.eclipse.ui.startup">
 <startup
 class="your class implementing IStartup"/>
</extension>

Class:

public class Startup implements IStartup
{
 @Override
 public void earlyStartup()
 {
 // you action
 }
}
