Referencing class resource in FXML

I have a JavaFX program that uses Maven, with a standard maven file tree:

enter image description here

How do I reference logo.png from within layout.fxml, assuming that layout is being inflated by a call to 

Parent root = FXMLLoader.load(getClass().getResource("/fxml/layout.fxml"));

in MainApp.

I've trying to do so using 

<image>
<Image url="@/graphics/logo.png" />
</image>

and have tried many variations on that file path (with and without the @), but keep throwing a 

java.lang.reflect.InvocationTargetException 
... 
Caused by: java.lang.IllegalArgumentException: URL must not be empty

on the line where the URL is created

You are trying to locate the image resource with name "backButton.png" whereas it should be "logo.png".

If the problem persists, try as

<Image url="@../graphics/logo.png" />

since from official FXML tutorial:

The location resolution operator (represented by an "@" prefix to the attribute value) is used to specify that an attribute value should be treated as a location relative to the current file rather than a simple string.
