scala.tools.reflect.ToolBoxError 异常

Question

我遇到了一个问题，无法解决。今天，我在构建项目时遇到错误。主题中描述了此错误：

据我所知，新版本的 scala 已发布 (2.12.0-M1) 并且依赖关系已被破坏。这个问题的答案是使用代码覆盖 "org.scala-lang" 和 "scala-compiler" 依赖项：

dependencyOverrides += "org.scala-lang" % "scala-compiler" % scalaVersion.value

我的 scalaVersion 是 scalaVersion := "2.11.1"。这解决了构建项目的问题。服务器成功运行，但是当我尝试调用 DB 对象（扩展 Instance）来执行查询时，我得到一个异常：

我认为这与 scala 更新和配置问题有关，因为昨天我使用相同的服务，没有任何异常。

我的build.sbt:

name := """XXXX"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.11.1"

dependencyOverrides += "org.scala-lang" % "scala-compiler" % scalaVersion.value

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws,
  "org.sorm-framework" % "sorm" % "0.3.18",
  "com.typesafe.play" %% "play-mailer" % "2.4.0",
  "com.typesafe.play" %% "play-json" % "2.3.7",
  "postgresql" % "postgresql" % "9.1-901.jdbc4",
  "com.sksamuel.scrimage" %% "scrimage-core" % "1.4.2",
  "com.sksamuel.scrimage" %% "scrimage-canvas" % "1.4.2",
  "com.sksamuel.scrimage" %% "scrimage-filters" % "1.4.2",
  "com.notnoop.apns" % "apns" % "1.0.0.Beta6",
  "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
)

知道为什么会这样吗？

谢谢

我有同样的错误。将 scalaVersion 增加到 2.11.6 解决了它。
