spring - 项目构建错误:org.springframework.cloud:'spring-cloud-starter-eureka-server:jar缺少'dependencies.dependency.version'

Question

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

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缺少'dependencies.dependency.version'。


另一个错误：

Answer 1

如我的评论所示，一些入门者已重命名：https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes


许多入门者未遵循正常的Spring Cloud命名约定。在Edgware中，使用不建议使用的启动程序将记录一个警告，并在该警告中使用要使用的新启动程序的名称。


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