If the above "wsdlLocation" doesn't work add "classpath:" before wsdl/adpetra.wsdl.

The above plugin creates the atrefact as below  

@WebServiceClient(name = "Adeptra", 
                  wsdlLocation = "wsdl/adeptra.wsdl",
                  targetNamespace = "http://www.adeptra.net/Adeptra/") 
public class Adeptra_Service extends Service {

    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName("http://www.adeptra.net/Adeptra/", "Adeptra");
    public final static QName AdeptraSOAP = new QName("http://www.adeptra.net/Adeptra/", "AdeptraSOAP");
    static {
        URL url = Adeptra_Service.class.getResource("wsdl/adeptra.wsdl");
        if (url == null) {
            url = Adeptra_Service.class.getClassLoader().getResource("wsdl/adeptra.wsdl");
        } 
        if (url == null) {
            java.util.logging.Logger.getLogger(Adeptra_Service.class.getName())
                .log(java.util.logging.Level.INFO, 
                     "Can not initialize the default wsdl from {0}", "wsdl/adeptra.wsdl");
        }       
        WSDL_LOCATION = url;
    }
