ScalaFX:HelloWorld编译错误 [英] ScalaFX: HelloWorld compilation error

问题描述

我是Scala和SBT的新手，所以我可能缺少明显的东西.

I'm new to Scala and SBT so I might be missing something obvious.

我试图在 http://www.scalafx.org/docs/上编译HelloWorld示例快速入门/

我创建了一个文件build.sbt，其中包含:

I created a file build.sbt containing:

scalaVersion := "2.11.5"

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

和包含链接页面中代码的文件src/main/scala/ScalaFXHelloWorld.scala.

and a file src/main/scala/ScalaFXHelloWorld.scala containing the code from linked page.

但是，当运行sbt run时，我得到:

However, when running sbt run I get:

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

我正在Archlinux的openjdk 1.8.0_31上运行sbt 0.13.7和scala 2.11.5

I'm running sbt 0.13.7 and scala 2.11.5 on openjdk 1.8.0_31 on Archlinux

推荐答案

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

JavaFX isn't part of OpenJDK 8. I installed openjfx. Works. (Thanks Jasper)
