Blueprints应用编程接口、addVertex的问题

Question

我刚刚遇到了一个关于BluePrints应用程序接口的问题。我已经执行了以下Scala命令：

val dbBasename = "C:\\Users\\taatoal1\\tmp\\orientdb\\databases\\"
val dbpath = "test_ingest"
val (uname, pwd) = ("admin", "admin")

val graph = new OrientGraph(s"plocal:$dbpath", uname, pwd)
graph.addVertex("class:Employee")

我得到了下面的错误

<console>:14: error: ambiguous reference to overloaded definition,
both method addVertex in class OrientBaseGraph of type (x$1: Any, x$2: <repeated...>[Object])com.tinkerpop.blueprints.impls.orient.OrientVertex
and  method addVertex in class OrientBaseGraph of type (x$1: Any)com.tinkerpop.blueprints.impls.orient.OrientVertex
match argument types (String)
              graph.addVertex("class:Employee")
                    ^

你知道我做错了什么吗？

提前感谢

最后，我发现还有另一个版本的addVertex，它接受两个字符串作为参数:类名和集群名。
