NoClassDefFoundError: kafka/manager/utils/TopicConfigs$

I'm having trouble getting kafka-manager up and running on my system. I've built the application using the instructions provided in the README however when I start the service I am unable to access the application on the specified port. Digging into the logs reveals only the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: kafka/manager/utils/TopicConfigs$

I'm running on RedHat Enterprise 6.8 with Oracle Java 1.8.0_65. Here are the steps I followed to get it running:

git clone https://github.com/yahoo/kafka-manager.git
cd kafka-manager
git checkout 1.3.0.8.1
./sbt clean dist
./sbt rpm:packageBuild
sudo rpm -ivh target/rpm/RPMS/noarch/kafka-manager-1.3.0.8-1.noarch.rpm
# now I update /etc/kafka-manager/application.conf & /etc/default/kafka-manager
sudo service kafka-manager start

The source code for the missing class is under app/kafka/manager/utils/TopicConfigs.scala however I can't seem to find the contents of that app directory. From what I can tell, kafka-manager was installed to /usr/share/kafka-manager however I don't see an app folder in there and I can't find the contents of the app directory in any of the jars in the lib directory.

Are there steps that I'm missing during the build/installation process? Any help on this would be greatly appreciated.
