我正在尝试为 Lift 框架启动一个基本的 sbt 构建并遇到以下错误：

[error] bad symbolic reference to scala.ScalaObject encountered in class file 'package.class'.
[error] Cannot access type ScalaObject in package scala. The current classpath may be
[error] missing a definition for scala.ScalaObject, or package.class may have been compiled against a version that's
[error] incompatible with the one found on the current classpath.
[error] one error found
[error] (compile:compile) Compilation failed
[error] Total time: 7 s, completed Aug 19, 2014 8:27:51 PM

这是我的构建文件，运行在sbt 0.13：

name := "MyApp"

version := "0.0.0"

organization := "com.myapp"

scalaVersion := "2.11.1"

EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Resource

resolvers ++= Seq("snapshots" at "http://oss.sonatype.org/content/repositories/snapshots",
                  "releases"  at "http://oss.sonatype.org/content/repositories/releases",
                  "releases"  at "http://oss.sonatype.org/content/repositories/releases"
                )

seq(webSettings :_*)

unmanagedResourceDirectories in Test <+= (baseDirectory) { _ / "src/main/webapp" }

scalacOptions ++= Seq("-deprecation", "-unchecked")

libraryDependencies ++= {
  val liftVersion = "2.6-RC1"
  Seq(
    "net.liftweb"       %% "lift-webkit"        % liftVersion        % "compile",
    "net.liftweb"       %% "lift-mapper"        % liftVersion        % "compile",
    "net.liftmodules"   % "lift-jquery-module_2.6_2.9.1-1" % "2.8",
    "org.eclipse.jetty" % "jetty-webapp"        % "9.2.2.v20140723"  % "container,test",
    "org.eclipse.jetty" % "jetty-plus"          % "9.2.2.v20140723"  % "container,test", // For Jetty Config
    "org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" % "container,test" artifacts Artifact("javax.servlet", "jar", "jar"),
    "org.specs2"        %% "specs2"             % "2.4.1"            % "test",
    "mysql" % "mysql-connector-java" % "5.1.+",
    "org.slf4j" % "slf4j-log4j12" % "1.7.+",
    "org.squeryl" % "squeryl_2.11" % "0.9.6-RC3"
  )
}

这里和这里有类似的问题，但我不明白答案，它们并没有帮助我解决问题。我最近都升级到 Scala2.11.1并升级了在 sbt 中声明的依赖项，但我不确定问题到底出在哪里。我的具体问题是：如何从上面的错误跟踪到导致此问题的依赖项？或者，如果它不是依赖问题，问题出在哪里，我如何确定问题在哪里？

快速浏览一下，您可能正在使用 Lift-JQuery 的 scala 2.9.1 版本。从他们的文档中：

对于版本 >= 2.3

"net.liftmodules" %% "moduleName_x1.y1 %​​ "x2.y2[.z2][-SNAPSHOT/rcx/mx]"

其中 x1.y1 是 Lift 主要和次要版本号，abc 是 Scala 版本号，x2.y2.[z2] 是模块的主要 x2、次要 y2 和最终增量编号 z2 后跟最终的 SNAPSHOT 候选版本 (rcX) 或里程碑(mX) 版本部分。

尝试："net.liftmodules" % "lift-jquery-module_2.6" % "2.8"可能会解决您的问题
