使用瘦ORM的Scala运行时问题

我是Skinny ORM的新手，我遇到了一个奇怪的问题。

我试图让一个小片段工作，SBT编译我的代码但是 我找不到运行时错误消息类。 （我收到的消息 通过Intellij运行

我的build.sbt： 

name := "skinny_jdbc"

version := "1.0"

scalaVersion := "2.12.1"


libraryDependencies ++= Seq(
  "org.skinny-framework" %% "skinny-orm"      % "2.3.2",
  "com.h2database"       %  "h2"              % "1.4.+",
  "ch.qos.logback"       %  "logback-classic" % "1.1.+"
)

我的测试应用 

import scalikejdbc._
import skinny.orm._, feature._
import org.joda.time._

object sk_test extends App{

  println ("In SK_test object")
  skinny.DBSettings.initialize()
  implicit val session = AutoSession

}

编译得很好 - 但我收到运行时错误 

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/pool/ObjectPool

详细信息如下。

先谢谢。

我相信您使用了网站上建议的application.conf。这应该可以正常工作。

development {
  db {
    default {
      driver="org.h2.Driver"
      url="jdbc:h2:file:./db/development;MODE=PostgreSQL;AUTO_SERVER=TRUE"
      user="sa"
      password="sa"
      poolInitialSize=2
      poolMaxSize=10
    }
  }
}

或者你必须在build.sbt中包含commons-dbcp以将库作为依赖项拉入
