Spring Cloud Eureka: Works with maven and in IDE, but not as uber-jar - spring-boot

Question

I have a sample Eureka server project, which works fine when run either in IntelliJ, or with "mvn spring-boot:run". However, when running the uber jar directly with "java -jar eureka-server-1.0-SNAPSHOT.jar", I'm getting the following stack trace:
2015-11-04 19:48:56.985 ERROR 138300 --- [ main] o.s.boot.SpringApplication : Application startup failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [org.springframework.cloud.netflix.eureka.server.EurekaServerConfiguration]; nested exception is java.lang.IllegalStateException: Annotation #EnableDiscoveryClient found, but there are no implementations.

So I do have a spring-cloud-starter-eureka-server starter dependency, plus I don't have #EnableDiscoveryClient annotation anywhere in the project.
Here is the only .java file in the whole project:
#SpringBootApplication
#EnableEurekaServer
public class EurekaApplication
{
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);;
}
}
Here is the application.properties file:
server.port=8761
eureka.client.registerWithEureka: false
eureka.client.fetchRegistry: false
eureka.server.waitTimeInMsWhenSyncEmpty: 0
Thank you in advance!

Eureka will not work with the jersey version you specify (it didn't for me).
Use http://start.spring.io to generate starting projects.
This pom.xml does work.
