Question

我遇到了问题，无法解决问题。今天，我在构建项目时遇到错误。主题中描述了此错误： Why do I get conflicting cross-version in sbt on one environment but not another?

据我所知，新版本的scala已经发布（2.12.0-M1）并且依赖性被破坏了。这个问题的答案是覆盖＆＃34; org.scala-lang＆＃34;和＆＃34; scala-compiler＆＃34;使用代码的依赖：

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。服务器运行成功，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：

我认为它与scala更新和配置问题有关，因为昨天我使用相同的服务，没有任何例外。

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"
)

为什么会发生这种情况？

谢谢

我有同样的错误。将scalaVersion增加到2.11.6解决了它。

scala.tools.reflect.ToolBoxError异常
