ARouter错误Failed resolution of ARouter$$Group

错误日志

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/alibaba/android/arouter/routes/ARouter$$Group$$order_service;

路由无法跳转或者外部无法调用子模块向外部暴露的服务，出现这种情况很可能是path路径分组重复，比如有A、B两个模块，则不能分别在A、B中这样定义

@Route(path = "/module/a")
@Route(path = "/module/b")

因为不同的module应该属于不同的分组

@Route(path = "/module1/a")
@Route(path = "/module2/b")
