Google clould endpoint Api method generated without the required parameter

问题

I want to deploy v2 of my google endpoint API. in this version 2, i have added an ApiMethod with a parameter

 /**
 * An endpoint class we are exposing
 */
@Api(
  name = "myApi",
  version = "v2",
  namespace = @ApiNamespace(
    ownerDomain = "awesome.me.com",
    ownerName = "awesome.me.com",
    packagePath = "api/v2"
  )
)
public class MyEndpointV2 extends MyEndpoint{


  @ApiMethod(name = "getContact")
  public Charges getContact(ContactRequest request){
    return ContactHandler.getContact(request);
  }
}

As you can see, my V2 extends my V1 Api so i can access all my V1 methods. the issue is that,my new method is generated without parameter ContactRequest. that is when i try to call the method in my app module, it appears as follows

myapi.getContact()

What could be the problem? I have tried to clean build my project but nothing happens

EDIT Here's MyEndPoint class

 @Api(
      name = "myApi",
      version = "v1",
      namespace = @ApiNamespace(
        ownerDomain = "awesome.me.com",
        ownerName = "awesome.me.com",
        packagePath = ""
      )
    )
    public class MyEndpoint{


     @ApiMethod(name = "getPeriod")
  public Period getPeriod(@Named("days")long days) {
    return Handler.getPeriod(days);
  }
  //other api methods
    }

This error may caused by your inheritance. Please read the following documentation

https://cloud.google.com/appengine/docs/java/endpoints/multiclass

It says that you have to use the same values for your annotations. You tried to override the values for Version and package. This can lead to undefined behaviour
