Question

我从start.spring.io创建一个Spring Boot 1.5.1项目，包括以下依赖项：Web，HATEOAS，Stream Kafka，Zookeeper配置，Zookeeper Discovery，Actuator。该服务本身就是一个Spring-cloud-stream测试服务。

在不更改生成代码的任何内容的情况下，在mvn package我收到以下消息。这只是一个警告，但自从编译其他maven项目后，我在其他项目中遇到了构建问题，我想解决它。（我试图通过从start.spring.io创建这个干净的项目来隔离问题。）

这是确切的警告日志，低于生成的pom.xml。请注意，dependencyManagement警告提到com.netflix.eureka，但在此项目中没有包含Eureka依赖项。

我还尝试从本地maven存储库中删除所有内容并重建，以确保它处于一致状态但仍然收到警告。

Answer 1

问题来自https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-dependencies/pom.xml#L273-L276

我在这里开了一个问题。 https://github.com/spring-cloud/spring-cloud-netflix/issues/1715

Answer 2

很可能是依赖项被另一个依赖项使用了我建议您首先通过在依赖树上进行搜索来找到问题。

mvn dependency:tree

看起来像spring-cloud-starter-zookeeper-discovery可能是罪魁祸首 https://cloud.spring.io/spring-cloud-zookeeper/

现在只需要找到排除它的内容。你接下来做什么可能会变得棘手，因为如果你排除它，zookeeper可能现在可以工作了
