Maven dependencyManagement WARNING on clean project generated from start.spring.io - maven

Question

I'm creating a Spring Boot 1.5.1 project from start.spring.io including the following dependencies: Web, HATEOAS, Stream Kafka, Zookeeper Configuration, Zookeeper Discovery, Actuator. The service itself is a spring-cloud-stream test service.
Without changing anything from the generated code, at mvn package I got the following message. It's just a warning, but since compiling other maven project I'm getting build problems in other projects I'd like to solve it. (I tried to isolate the problem by creating this clean project from start.spring.io).
This is the exact Warning log, and below the generated pom.xml. Notice that the dependencyManagement warning mentions com.netflix.eureka, but in this project no Eureka dependencies have been included.
I also tried to remove all contents from the local maven repository and rebuild, to make sure this is in a consistent state but kept getting the warning.

Answer 1

The issue comes from https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-dependencies/pom.xml#L273-L276
I've opened an issue here. https://github.com/spring-cloud/spring-cloud-netflix/issues/1715

Answer 2

it's very likely that the dependency is being used by another dependency I recommend you first find the issue by doing a search on your dependency tree.
mvn dependency:tree
looks like spring-cloud-starter-zookeeper-discovery might be the culprit
https://cloud.spring.io/spring-cloud-zookeeper/
now it's just a matter of finding what is excluding it. What you do next might get tricky because if you exclude it, zookeeper might now work anymore
