解决“Failed to read artifact descriptor for org.springframework.cloud:spring-cloud-st”

本文主要是介绍解决“Failed to read artifact descriptor for org.springframework.cloud:spring-cloud-st”，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

今天在建立eureka微服务过程中，pom文件中一直报“Failed to read artifact descriptor for org.springframework.cloud:spring-cloud-st”的错误，并且在启动类上添加注解@EnableEurekaServer，显示不存在该注解。原因是没有正确导入eureka需要的依赖。

eureka微服务中pom文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.lzj.springcloud</groupId><artifactId>microservice-parent</artifactId><version>0.0.1-SNAPSHOT</version></parent><artifactId>microservice-eurake1</artifactId><dependencies><!--eureka-server服务端 --><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka-server</artifactId></dependency><!-- 修改后立即生效，热部署 --><dependency><groupId>org.springframework</groupId><artifactId>springloaded</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId></dependency></dependencies></project>

在依赖的父工程microservice-parent工程中已经导入了SpringCloud版本，所以在eureka微服务中的pom文件中就不需要再导入SpringCloud了，父工程导入的SpringCloud版本为

            <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>Dalston.SR1</version><type>pom</type><scope>import</scope></dependency>

但是按上面的进行配置完后，eureka的pom文件上一直提示“Failed to read artifact descriptor for org.springframework.cloud:spring-cloud-st”的错误，并且在启动类上也没有@EnableEurekaServer注解。猜测应该是SpringCloud版本的原因，导致的eureka的依赖包的方式不正确，把eureka微服务中的pom文件改成如下就可以了，问题就完美的解决了。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.lzj.springcloud</groupId><artifactId>microservice-parent</artifactId><version>0.0.1-SNAPSHOT</version></parent><artifactId>microservice-eurake1</artifactId><dependencies><!--eureka-server服务端 --><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-netflix-eureka-server</artifactId></dependency><!-- 修改后立即生效，热部署 --><dependency><groupId>org.springframework</groupId><artifactId>springloaded</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId></dependency></dependencies></project>
