Describe the bug

同一个dubbo服务，有两个版本，在service注解中使用不同的group和version，但是在消费端使用Reference注解，指定引用其中一个group和version启动报错，把不引用的再nacos中下线，则可以正常启动

two dubbo provider,same project name,but have diff provider group and version,consumer Reference one of the group and version,Not found exported service

希望同一服务的service可以支持不同版本同时在线，调用端根据service的group和version调用不同的服务
