如何使用幻像斯卡拉主要對象

Question

我想使用幻像來處理我的卡桑德拉 這是我的例子來學習怎麼用幻影（感謝蒂亞戈）

https://github.com/thiagoandrade6/cassandra-phantom

我可以成功運行'SongTest'。

但我在我的scala主對象中運行database.create有些麻煩。 'scalatest'中的相同代碼已成功運行。但在我的Scala主要對象中，它失敗了。 這是我的源代碼

package com.cassandra.phantom.modeling 

import com.cassandra.phantom.modeling.database._ 
import com.cassandra.phantom.modeling.connector._ 
import scala.concurrent.ExecutionContext.Implicits.global 
import scala.concurrent.duration._ 
/** 
    * Created by karamko on 2017. 3. 28.. 
    */ 

class TestCass extends EmbeddedDatabase with Connector.connector.Connector { 
    def create() { 
    database.create(5.seconds) 
    } 
} 

object Main extends App{ 
    val test = new TestCass 
    test.create() 
} 

，這是我的錯誤

我解決我的問題添加下面的依賴

libraryDependencies += "org.scala-lang" % "scala-reflect" % scalaVersion.value 

非常感謝
