-> 尽管定义了 dalston 版本，但根据错误缺少 Zuul jar [错误]

从 spring-snapshots 下载：https://repo.spring.io/snapshot/org/springframework/cloud/spring-cloud-dependencies/Dalston.BUILD-SNAPSHOT/spring-cloud-dependencies-Dalston.BUILD-SNAPSHOT.pom [错误] [错误] 处理 POM 时遇到一些问题： [错误] 不可解析的导入 POM：无法将工件 org.springframework.cloud:spring-cloud-dependencies:pom:Dalston.BUILD-SNAPSHOT 从/向 spring-snapshots (https://repo.spring.io/snapshot) 传输：https://repo.spring.io/snapshot/org/springframework/cloud/spring-cloud-dependencies/Dalston.BUILD-SNAPSHOT/spring-cloud-dependencies-Dalston.BUILD-SNAPSHOT.pom 传输失败ProxyInfohost='cinext11.proxy.corporate.ge.com', userName='null', port=80, type='https', nonProxyHosts='null' @ 第 111 行，第 16 列 [错误] org.springframework.cloud:spring-cloud-starter-zuul:jar 的“dependencies.dependency.version”缺失。 @ 第 28 行，第 15 列

【问题讨论】：

请尝试提出更明确的问题。你想达到什么目标，什么是行不通的？

您要查找的版本不存在：repo.spring.io/snapshot/org/springframework/cloud/…

@TobiO ，如上所述，当我使用 MVN 全新安装时，出现了错误消息。

@SiKing 您评论中提供的链接确实包含在我的 POM.xml 中使用的 Dalston.BUILD-SNAPSHOT/ 版本。

但是根据错误，缺少的依赖项是版本“Greenwich.SR1”。这可能是作为传递依赖被拉取的。

【参考方案1】：

Spring-Cloud 的 Dalston 发布火车于 2016 年发布。 你不应该再使用它的 SNAPSHOT 版本了。

从 2017 年 12 月开始发布 Dalston.SR5，这将导致：

spring-cloud-dependencies:Dalston.SR5
-> spring-cloud-netflix-dependencies:1.3.6.RELEASE
-> spring-cloud-starter-zuul:1.3.6.RELEASE
-> zuul-core:1.3.0

如果您开始一个新项目并且您拥有 Spring Boot 2.2.x，您还可以使用最新的发布系列 (Hoxton)。然而，Spring Cloud 从未升级到 Netflix Zuul 2，但发布了替代方案：Spring-Cloud-Gateway。见How is Spring Cloud Gateway different from Zuul?

底线：避免依赖 spring-snapshots 或 spring-milestones 存储库，除非您需要前沿版本。
