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"

和一个文件 src/main/scala/ScalaFXHelloWorld.scala包含来自链接页面的代码。

但是，运行时 sbt run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。 (感谢贾斯珀)
