Question

我试图为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，在sbt 0.13下运行：

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"
  )
}

有类似的问题here和here，但我不理解答案，他们并没有帮我解决问题。我最近都升级到Scala 2.11.1并升级了sbt中声明的依赖项，但我不确定问题实际出现在哪里。我的具体问题是：如何从上面的错误跟踪导致此问题的依赖项？或者，如果它不是依赖问题，问题在哪里，我如何确定它在哪里？

快速浏览一下，您可能正在使用Scala 2.9.1版本的Lift-JQuery。来自他们的文档：

对于版本＆gt; = 2.3

“net.liftmodules”%%“moduleName_x1.y1％   “x2.y2 [.z2] [ - 快照/ RCX / MX]”

其中x1.y1是Lift主要和次要版本号，a.b.c是Scala   版本号和x2.y2。[z2]是模块的主要x2，次要y2和   最终的增量数字z2，然后是最终的SNAPSHOT   发布候选者（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

对scala.ScalaObject的错误符号引用
