Question

我正在使用OrientDB Native Java Driver与Orient DB Server进行简单连接。我正在关注OrientDb Github link以获取基本设置说明。我添加了github链接中提到的五个jar，orient-commons-*.jar, orientdb-core-*.jar, orientdb-object-*.jar, orientdb-client-*.jar, orientdb-enterprise-*.jar。但是，我仍面临以下错误。我用谷歌搜索，找不到任何关于哪个jar文件丢失的答案？请指教。

不确定这是否会对您有所帮助，但看起来您提到的课程是在“concurrentlinkedhashmap-lru-1.1.jar”中

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

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