dubbo3.1.7 dubbo-metrics-prometheus 使用问题

dubbo3.1.7 集成 dubbo-metrics-prometheus， 采集不到dubbo相关的指标
dubbo.metrics.protocol=prometheus
相关jar包也都根据 官方示例引用，但是没有dubbo的指标，这是什么情况

No source file or test is named. Start by reproducing the issue with Dubbo 3.1.7, the documented dubbo-metrics-prometheus dependencies, and dubbo.metrics.protocol=prometheus; inspect the metrics integration and its exposed endpoint. Done means Dubbo-related metrics are collected, or the cause and required configuration are documented.
