How to add custom widget

I create a main web projet and  create a new project for my custom component.
I have added reference to my component in my web.xml

<init-param>
<param-name>widgetset</param-name>
<param-value>com.mycompany.web.stest.STestWidgetset</param-value>
</init-param>

I have added dependency to my component in the pom.xml too

<dependency>
<groupId>com.mycompany.web.stest</groupId>
<artifactId>stest</artifactId>
<version>${app-version}</version>
<type>jar</type>
</dependency>

Application is running fine but when I go to debug mode component is not taken my custom Connector
I don't what I made wrong
I quite new in Vaadin

Thanks to all for your help.

Try running mvn vaadin:update-widgetset, it should update your widgetset definition file. After that running, mvn vaadin:compile should recompile the widgetset for you.

If everything goes well, the widget should now be compiled as a part of the widgetset and the connector will be found.

Thank you Aali for your help I try and let you know
