Sprint and Element Api


I’m new to Vaadin and Polymer.

In Java EE, I followed the tutorials and everything works perfect, but in Sprint certain options change.

In Java EE, if I want to use a simple element I do the following:

public class PaperInput extends Component implements HasSize

What is the procedure in Sprint, since I use Maven instead of Bower, and I do not know what the HtmlImport path is?
