Project build error: 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-eureka-server:jar is missing

提问by Jeff Cook

I am developing a code from https://www.dineshonjava.com/microservices-with-spring-boot/. When I update the spring-boot-starter-parent from 1.5.4.RELEASEto 2.0.4.RELEASE, build got failed.

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

Could anyone please guide me what is the issue ?

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

As indicated in my comment, some starters were renamed: https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes

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

A number of starters did not follow normal Spring Cloud naming conventions. In Edgware, use of the deprecated starter will log a warning with the name of the new starter to use in its place.

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 将记录一条警告，其中包含要在其位置使用的新 starter 的名称。

So change: spring-cloud-starter-eureka-serverto spring-cloud-starter-netflix-eureka-server.

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

Even I got the similar error when I was adding dependency for hystrix.

甚至当我为hystrix.

Error : Project build error: 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-hystrix:jar is missing

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

It worked after changing netflix <artifactId>

更换netflix后就可以了 <artifactId>

from: spring-cloud-starter-hystrix 
to:   spring-cloud-starter-netflix-hystrix

1o) remove dependency from your pom.xml and save the file;

1o) 从您的 pom.xml 中删除依赖项并保存文件；

2o) Go to the STS project > right click > Spring > Edit Starters > search to Eureka Discovery Clientand mark checkbok > OK.

2o) 转到 STS 项目 > 右键单击​​ > Spring > 编辑 Starters > 搜索Eureka Discovery Client并标记 checkbok > OK。

This action solved my problem.
