在OS X上为Java 7u7(包含JavaFX 2.2)编译scalafx [英] Compiling scalafx for Java 7u7 (that contains JavaFX 2.2) on OS X

问题描述

scalafx 的编译说明指出:

export JAVAFX_HOME=/Path/To/javafx-sdk2.1.0-beta
sbt clean compile package make-pom package-src

但是，随着JavaFX新包装作为Java JDK本身的一部分(即OS X为7u7)，似乎不再有这样的"javafx-sdkx.x.x"文件夹. Oracle文档说JavaFX JDK与主要Java JDK放在同一文件夹中.

However, with the new packaging of JavaFX as part of the Java JDK itself (i.e. 7u7 for OS X) there no longer seems to be such a 'javafx-sdkx.x.x' folder. The Oracle docs say that JavaFX JDK is placed alongside the main Java JDK (in same folders).

所以我这样做:

$ export JAVAFX_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk
$ sbt clean
[warn] Using project/plugins/ (/Users/asko/Sources/scalafx/project/plugins) for plugin configuration is deprecated.
[warn] Put .sbt plugin definitions directly in project/,
[warn]   .scala plugin definitions in project/project/,
[warn]   and remove the project/plugins/ directory.
[info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins/project

[error] java.lang.NullPointerException
[error] Use 'last' for the full log.
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? 

我做错什么了吗?或者scalafx尚未与最新的Java版本(7u7，JavaFX 2.2)兼容.我该怎么办?

Am I doing something wrong or is scalafx not yet compatible with the latest Java release (7u7, JavaFX 2.2). What can I do?

附录

..最后(按照下面的Igor解决方案)，sbt run轻松启动彩色圆圈演示(好吧，如果一个人具有受支持的GPU). Oracle "JavaFX支持的声明狮子或更高版本的任何Mac OS X系统上的图形硬件加速".但我倾向于认为我所使用的NVidia驱动的Mac Mini可以进行软件渲染.

..and finally (following Igor's solution below) sbt run launches the colorful circles demo easily (well, if one has a supported GPU that is). Oracle claims that "JavaFX supports graphic hardware acceleration on any Mac OS X system that is Lion or later" but I am inclined to think the NVidia powered Mac Mini I'm using does software rendering.

不，即使是本来可以快速使用Javafx的MacBook Air(酷睿i7)在演示中也很迟钝.也许是演示.

Nope, even the otherwise fast-with-javafx MacBook Air (core i7) is sluggish with the demo. Maybe it's the demo.

推荐答案

我所做的是:

hg clone https://code.google.com/p/scalafx/
cd scalafx
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home
sbt clean compile package make-pom package-src

有效. 似乎最新的代码签出包含对与SDK捆绑在一起的JavaFX的支持.检查build.sbt文件的第106行.

It works. It seems that the latest code checkout contains support for JavaFX bundled with the SDK. Check the build.sbt file, line 106.
