After adding the Kafka test dependencies (https://github.com/aerogear/aerogear-unifiedpush-server/pull/848/commits/ff104bb98c37876e877b48f0e86f64ef7d82d91d) the build fails with the following error:

org.apache.maven.lifecycle.LifecycleExecutionException:
Failed to execute goal com.qmino:miredot-plugin:1.6.1:restdoc (default) on project unifiedpush-jaxrs:
Execution default of goal com.qmino:miredot-plugin:1.6.1:restdoc failed:
A required class was missing while executing com.qmino:miredot-plugin:1.6.1:restdoc: com/fasterxml/jackson/core/type/TypeReference

It works when I add the dependency it's complaining about, but I'm not sure why this happens and how to figure out which dependency (or if all of them) are clashing with the existing ones. Any ideas Polina Koleva ??

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.9.0.pr4</version>
</dependency>
