pom.xml 每次添加新依赖时都会出错

【中文标题】pom.xml 每次添加新依赖时都会出错

【英文标题】：pom.xml gives error every time on adding new dependency

【发布时间】：2020-01-20 02:21:24

【问题描述】：

我有一个 pom.xml 文件错误，其中包含依赖项/插件。每次我添加新的依赖项时，它都会给出与版本相关的错误。目前它给出了与 Eureka 服务器相关的错误。

在 pom.xml 中为 Eureka 命名服务器添加依赖项后的错误消息

项目构建错误：org.springframework.cloud:spring-cloud-starter-eureka:jar 的“dependencies.dependency.version”缺失。

pom.xml 文件：

【问题讨论】：

spring-cloud-starter-eureka is not resolving when i use Finchley.M5 和/或 ***.com/questions/51921033/… 的可能重复

【参考方案1】：

该依赖已被弃用，因此它不包含在导入的依赖管理中，另请参阅https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka 处的备注：

Spring Cloud Starter Eureka（已弃用，请使用 spring-cloud-starter-netflix-eureka-client

所以只需使用：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
