Method does not override or implement a method from a supertype

I'm creating a converter and it's giving me this error:

  

Method does not override or implement a method from a supertype

Converter code:

package com.mycompany.conversor;

import com.mycompany.entidades.agendaTipo;
import com.mycompany.repositorio.agendaTipoRepositorio;
import java.lang.annotation.Annotation;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.FacesConverter;
import javax.inject.Inject;
import javax.persistence.Converter;


@FacesConverter(forClass = agendaTipo.class)
public class agendaTipoConverter implements Converter{

    @Inject
    private agendaTipoRepositorio agendaTipoRepositorio;

    @Override
    public Object getAsObject(FacesContext context,
    UIComponent component, String value) {
        agendaTipo retorno = null;
        if (value != null && !"".equals(value)) {
            retorno = this.agendaTipoRepositorio.porId(new Long(value));
        }
        return retorno;
    }

    @Override
    public String getAsString(FacesContext context,
    UIComponent component, Object value) {
        if (value != null) {
            agendaTipo agendaTipo = ((agendaTipo) value);
            return agendaTipo.getId() == null ? null : agendaTipo.getId().toString();
        }
        return null;
    }
}
