我想将日历（https://vaadin.com/directory/component/calendar-add-on）添加到我的项目中。因此，我已将依存关系添加到pom.xml中。
当我使用日历组件运行项目时，出现错误，组件在哪里：
Widgetset'com.vaadin.DefaultWidgetSet'不包含
org.vaadin.addon.calendar.Calendar的网站：vaadin.com
我读过某个地方，我需要在配置中添加“不存在的模块”，然后编译widgetset。
所以我做到了，现在当我编译widgetset时，它给了我一个JS解析器错误。
难道我做错了什么？
这是widgetset的编译输出：

最佳答案
好。工作正常！
我将pom中的“不存在的模块”更改为“ MyWidgetset.Widgetset.gwt.xml”，然后将注释@Widgetset（“ MyWidgetset.Widgetset.gwt.xml”）添加到UI类。
