<dependency>
         <groupId>com.alibaba.cloud</groupId>
         <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
     </dependency>

项目中pom.xml直接用这个maven会报  
`Could not find artifact com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-discovery:pom:unknown in aliyun-public (https://maven.aliyun.com/repository/public)`

试了几种方法包括：

1.  指定版本为1.4.1
2.  在.m2/settings.xml里添加新的阿里云源
3.  Invalid cache重启
4.  maven clean

发现都没用。最终解决方法是在pom的dependencyManagement添加

<dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${spring-cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>${spring-cloud-alibaba.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

$\{spring-cloud-alibaba.version\} 要根据对应的springboot版本来选。详见[springcloud alibaba 版本说明][springcloud alibaba]
