scala.tools.reflect.ToolBoxError异常

我被一个问题缠住了，无法解决它。 今天，我在构建项目时出错。主题中描述了此错误：

据我所知，scala的新版本已经发布（2.12.0-M1），依赖关系也被打破。 这个问题的答案是使用以下代码重写“org.scala lang”和“scala编译器”依赖关系：

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

我的scalaVersion是

scalaVersion:=“2.11.1”

。 这解决了建设该项目的问题。 服务器运行成功，但当我尝试调用

DB

对象（扩展

实例

）以执行查询时，出现异常：

我认为这与scala更新和配置问题有关，因为昨天我毫无例外地使用了相同的服务

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",

)

你知道为什么会这样吗

---

谢谢你，我也犯了同样的错误。将scala-compiler.jar的版本增加到2.11.6解决了这个问题。

这可能是您的项目特有的，所以很难说为什么没有完整的

build.sbt

，但发生的情况是，在ClassPath中有几个版本的scala-compiler.jar。谈到链接的问题，您是否尝试清除缓存、目标、sbt的项目目标？谢谢，我将思考为什么在我的类路径中有几个scala-compiler.jar。我还用

build.sbt

contentDeleted

$HOME/.ivy2/cache

和目标文件夹更新了任务，但没有成功，相同的例外我在前面通过从

build.sbt

提取SORM并添加棘手的被黑客攻击的SORM.jar文件作为外部库解决了这个问题。现在我回到了

libraryDependencies

中使用SORM的更简单的解决方案，这很好。非常感谢。我使用的是2.11.12，但仍然会出现此错误。
