Spring cloud Eureka error when running

Question

I'm trying to create a Spring cloud Eureka server with the pom below, largely derived from https://github.com/joshlong/service-registration-and-discovery

However, I'm getting "Error creating bean with name 'viewControllerHandlerMapping'" error, caused by "java.lang.IllegalStateException: The resources may not be accessed if they are not currently started".

Which I think may have to do with versions for various Jersey components pulled being 1.11 and 1.13, although I don't see any single jar being pulled twice. Other than that, I have no clue why. Any ideas? Thanks in advance!

Answer 1

So the problem is that spring-cloud-starter-eureka-server 1.0.3.RELEASE is pulling conflicting jersey versions -- 1.11 and 1.13. If I exclude 1.13 dependencies and re-add them as 1.11 dependencies, it works:

Conflicting jersey versions:

[INFO] |  +- org.springframework.cloud:spring-cloud-netflix-eureka-server:jar:1.0.3.RELEASE:compile
[INFO] |  |  +- com.netflix.eureka:eureka-client:jar:1.1.147:compile
[INFO] |  |  |  +- com.sun.jersey:jersey-core:jar:1.11:compile
