Extending Eclipse with scripting language?

Is it possible to add some functionality to the Eclipse IDE using a
scripting language of some kind instead of making changes to the Java
sources and recompiling the whole thing?

As an example, I would like to invoke an add-on inspector in the
debugger without having to use the Execute option on this code
Inspector.inspect(object) each time. It would be wonderful if I could
add a hotkey or menu item that could open the inspector.

Thanks,
