Question

我有一个应该创建一个可运行的jar文件的sbt项目。正确创建jar时，启动它时会抛出一个异常：

我认为这是一个奇怪的错误，因为该类应该在标准库中。我还尝试使用程序集构建一个jar文件，这会产生同样的问题。

这是我的build.sbt

import com.github.retronym.SbtOneJar._

name := "politodownloader"

version := "0.1.0"

//scalaVersion := "2.10.2"

scalaVersion := "2.11.2"

oneJarSettings

scalacOptions := Seq("-deprecation", "-unchecked", "-feature")

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"


resolvers += "spray" at "http://repo.spray.io/"

libraryDependencies ++= Seq(
  //"org.scalatest" % "scalatest_2.10" % "2.0" % "test" withSources() withJavadoc(),
  //"org.scalacheck" % "scalacheck_2.10" % "1.10.0" % "test" withSources() withJavadoc(),

)

mainClass in Compile := Some("io.clynamen.github.PolitoDownloader.Gui.MainWindow")

mainClass in oneJar := Some("io.clynamen.github.PolitoDownloader.Gui.MainWindow")

initialCommands := "import io.clynamen.github.PolitoDownloader._"

std lib的部分内容在2.11中分发。

对于org.scala-lang.modules组，有scala-xml，scala-parser-combinators等工件，每个都是单独版本化的。

好的，就是：

http://mvnrepository.com/artifact/org.scala-lang.modules/scala-parser-combinators_2.11/1.0.2

启动使用one-jar创建的jar时出错
