java.lang.NoClassDefFoundError: com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$Builder

问题

I am using OrientDB Native Java Driver for a simple connection to Orient DB Server. I am following OrientDb Github link for basic setup instructions. I have added the five jars mentioned in the github link, orient-commons-*.jar, orientdb-core-*.jar, orientdb-object-*.jar, orientdb-client-*.jar, orientdb-enterprise-*.jar. However, I am still facing below error. I googled and couldn't find any answer regarding which jar file am I missing? Please advise.

not sure whether this will help you or not but looks like the class you mentioned is in the "concurrentlinkedhashmap-lru-1.1.jar"

http://mvnrepository.com/artifact/com.googlecode.concurrentlinkedhashmap/concurrentlinkedhashmap-lru/1.1
