Vaadin：日历插件的问题-无法编译窗口小部件集

Question

I've wanted to add Calendar ( https://vaadin.com/directory/component/calendar-add-on ) to my project. So I've added dependency to my pom.xml.
When I run project with calendar component I've got error in place, where component was:

Widgetset 'com.vaadin.DefaultWidgetSet' does not contain an implementation for org.vaadin.addon.calendar.Calendar site:vaadin.com

I've read somewhere that I need to add "non-existing-module" to configuration and then compile widgetset.
So I did that and now when I compile widgetset it gives me a JS parser error.
Am I doing something wrong?
Here is widgetset compiling output:

Answer 1

OK. It's working! I changed "non-existing-module" in pom to "MyWidgetset.Widgetset.gwt.xml" and then added annotation @Widgetset("MyWidgetset.Widgetset.gwt.xml") to UI class.
