Why isn't JavaFX on the jdk1.7.0_u10build12 class path?

[Scott Palmer]

I'm no Maven expert (in fact I hate it with a passion - it's fragile half-baked plugins broke the build on me just today) but what I suggested would continue to work without modifications after the proper co-bundling would it not?

The issue with including jfxrt.jar yourself is the fragile nature of the native code loading.  You must ensure the native libraries are at exactly the right relative path to jfxrt.jar.  If they aren't you might accidentally pick up the native libraries in the JRE folder and be fooled into thinking things are working.  Then when the JRE is updated the native libraries don't match your bundled jfxrt.jar and it breaks.  It happened to me :-) 
If you are't going to require 7u7 or later, it is probably best to use the javafxpackager tools somehow.
