ScalaFX:HelloWorld编译错误

Question

我是Scala和SBT的新手,所以我可能会遗漏一些明显的东西.

我试图在http://www.scalafx.org/docs/quickstart/上编译HelloWorld示例

我创建了一个文件build.sbt包含:

scalaVersion := "2.11.5"

libraryDependencies += "org.scalafx" %% "scalafx" % "8.0.0-R4"

以及src/main/scala/ScalaFXHelloWorld.scala包含链接页面代码的文件.

但是,当sbt run我跑步时,我得到:

OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

我在Archlinux上的openjdk 1.8.0_31上运行sbt 0.13.7和scala 2.11.5

JavaFX不是OpenJDK 8的一部分.我安装了openjfx.作品.(谢谢贾斯珀)
