Can't use @EnableEurekaClient to register config server with Eureka

[jogjayr]

Made a small project demonstrating the issue: https://github.com/jogjayr/config-and-discover

Adding the @EnableEurekaClient annotation to a config server application causes the following exception on startup:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.eurekaClient' defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.discovery.EurekaClient]: Factory method 'eurekaClient' threw exception; nested exception is java.lang.RuntimeException: Failed to initialize DiscoveryClient!

[spencergibb]

Looks like you are either missing Jackson or have an incompatible version.

[jogjayr]

@spencergibb Is there any guidance on what are compatible versions of config-server and Eureka client?

The only other project I've found attempting to do this is: https://github.com/KramKroc/eurekafirstdiscovery linked from #275 where it does work. However, it uses older versions of config server and Eureka client.

[spencergibb]

All dependencies should be find if you are using the bom (spring-cloud-dependencies).

[jogjayr]

Thanks @spencergibb that's what I ended up doing; figured it out a few hours ago. Chalk it up to my inexperience with how Maven works. Mean to leave a comment and close (even had it typed out) but managed to close the tab and forget about it somehow.

For Maven newbs having the same problem in future, here's what I did
