JSClipboard - Widgetset won't compile

Trying to use JSClipboard add-on but it does not include the gwt.xml and you can't compile the widgetset.  Any ideas?  Is it just missing?

-build-widgetset-1:
     [java] Loading inherited module 'com.dmb.ui.widgetset.Ui_projectWidgetset'
     [java]    Loading inherited module 'com.vaadin.jsclipboard.widgetset.JSClipboard'
     [java]       [ERROR] Unable to find 'com/vaadin/jsclipboard/widgetset/JSClipboard.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

BUILD FAILED

Found the widgetset build problem. It was the configuration on the dependency in Ivy.

But the plugin does not work.  Tried Chrome, Firefox and IE.

final JSClipboard clipboard = new JSClipboard();
clipboard.setText( "Some text" );
