Could you explain me how to install this addon?
I did a import to pom.xml and then pasted a folder to my project with three classes like Meeting.java, MeetingCalendar.java and MeetingItem.java.
But when I try to initialize Calendar like in Your demo:
// Initialize our new UI component
MeetingCalendar meetings = new MeetingCalendar();
meetings.setSizeFull();
I got error:
java.lang.NoSuchMethodError: 'com.vaadin.shared.Registration org.vaadin.addon.calendar.Calendar.addListener(java.lang.String, java.lang.Class, com.vaadin.event.SerializableEventListener, java.lang.reflect.Method)'

I got same error when I try to just copy your DemoUI.java and paste to my project
Something is wrong in initCalendar() method with this line:
calendar = new Calendar<>(eventProvider);
