How are you running Kafdrop? Were there any errors during the build? This should be all you need (using latest master branch):

mvn clean install
java -jar target/kafdrop-1.2.2-SNAPSHOT.jar --zookeeper.connect=<ZK_HOST:ZK_PORT>

Thanks for quick turnaround. I ran build again and it's working fine now.
