maven阿里云镜像找不到nacos的jar包
提示： com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-discovery:jar:unknown was not found in maven.aliyun.com/repository/… during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of aliyunmaven has elapsed or updates are forced
解决方法：
在服务父工程中添加spring-cloud-alibaba的管理依赖
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>2.2.5.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
