scala - 启动使用 SORM 框架的 Scala 项目时出错

Question

我已经从 tutorial 创建了简单的 sbt 项目:

build.sbt:

lazy val sorm_test = (project in file(".")).
settings(
  name := "SORM_TEST",
  scalaVersion := "2.11.7",
  libraryDependencies ++= Seq(
    "org.sorm-framework" % "sorm" % "0.3.18",
    "com.h2database" % "h2" % "1.4.188"
  )
)

测试.Main.scala:

package test

case class Artist(
  names : Map[Locale, Seq[String]],
  genres : Set[Genre]
)

case class Genre(
  names : Map[Locale, Seq[String]]
)

case class Locale(
  code : String
)

import sorm._

object Db extends Instance(
  entities = Set(
    Entity[Artist](),
    Entity[Genre](),
    Entity[Locale](unique = Set() + Seq("code"))
  ),
  url = "jdbc:h2:mem:test",
  user = "",
  password = "",
  initMode = InitMode.Create
)

object Main extends App {
  // init
  Db.##
}

当我在 intellij 中运行这个项目时，我有这样的异常(exception):

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

当我使用 sbt run 时没问题。当我将 SORM 与 Play 框架集成时也会抛出此异常。我怎么解决这个问题 ？

Answer 1

我通过将 dependencyOverrides += "org.scala-lang"% "scala-compiler"% scalaVersion.value 添加到我的 sbt 配置中解决了这个问题。
