Error creating bean with name 'bindingService' - Eureka & Bus AMQP
<p>I'm trying to integrate Hystrix into my current spring-cloud &amp; Netflix OSS microservice project.</p>

<p>I have a fresh Spring Boot version 1.4.0.RELEASE project with two dependencies: </p>

<pre><code>    &lt;dependency&gt;
        &lt;groupId&gt;org.springframework.cloud&lt;/groupId&gt;
        &lt;artifactId&gt;spring-cloud-starter-eureka&lt;/artifactId&gt;
    &lt;/dependency&gt;
    &lt;dependency&gt;
        &lt;groupId&gt;org.springframework.cloud&lt;/groupId&gt;
        &lt;artifactId&gt;spring-cloud-starter-bus-amqp&lt;/artifactId&gt;
    &lt;/dependency&gt;
</code></pre>

<p>On project startup I receive this exception:</p>

<pre><code>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bindingService' defined in class path resource [org/springframework/cloud/stream/config/ChannelBindingServiceConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.stream.binding.ChannelBindingService]: Factory method 'bindingService' threw exception; nested exception is java.lang.NoClassDefFoundError: javax/validation/Validator
</code></pre>

<p>This exception only occurs when both the Eureka &amp; Bus AMQP dependencies are together.</p>

<p>There is no configuration set in application or bootstrap .yml/.properties.</p>

<p>The only Java class present is the one generated by Spring Boot:</p>

<pre><code>@SpringBootApplication
public class DummyProjectApplication {

    public static void main(String[] args) {
        SpringApplication.run(DummyProjectApplication.class, args);
    }
}
</code></pre>
