Generate WSDL interfaces with Maven in Eclipse - eclipse

Question

I am trying to develop a Soap web service, I created a UsersWS.wsdl file and now I need to generate the UsersWS interface to implements my UserWSImpl.java class. I tried some tutorials and plugins but nothing worked for me, can anyone help me ?
this is my POM.xml file
