This is my codes.

@rest(rootUrl = "**_", converters = { MappingJacksonHttpMessageConverter.class })
public interface ***_Service {

@Get("/1.0/member_login?username={user}&password={pwd}")
@SetsCookie("auth_token")
public void verifyUser(String user, String pwd);

@Get("/1.0/customer")
@RequiresCookie("auth_token")
public Customer getCustomerDetail();

// void setCookie(String name, String value);
//
String getCookie(String name);
}

I got this excepetion when I used mvn install command:
