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

问题描述

我正在从https://www.dineshonjava.com/microservices-with-spring-boot/开发代码。当我将 spring-boot-starter-parent 从更新1.5.4.RELEASE为 时2.0.4.RELEASE，构建失败了。

谁能指导我这是什么问题？

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

另一个错误：

解决方案

正如我的评论中所指出的，一些初学者被重命名：https ://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes

许多初学者没有遵循正常的 Spring Cloud 命名约定。在 Edgware 中，使用已弃用的 starter 将记录一个警告，其中包含要在其位置使用的新 starter 的名称。

所以改变： spring-cloud-starter-eureka-server 到spring-cloud-starter-netflix-eureka-server.
