问题
The compilation instructions of scalafx says to do:
export JAVAFX_HOME=/Path/To/javafx-sdk2.1.0-beta
sbt clean compile package make-pom package-src
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).
So I do:
$ 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 [info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins [error] java.lang.NullPointerException [error] Use 'last' for the full log. Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?
Am I doing something wrong or is scalafx not yet compatible with the latest Java release (7u7, JavaFX 2.2). What can I do?

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

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

There is also a Grade build.gradle in the ScalaFX, which I put there as an alternative build system
