Compiling using javac

Hi Graham,

Its really difficult to help without checking out the failing command first.

Could you reply back with the "javac" command you are trying to execute, along with the stacktrace?

Thank you, I'd already found this, but it isn't exactly "documentation." Also,
it is for Linux (Windows doesn't have export,) but I have put the path directly
on the --module-path option, which should be equivalent for this.

Crucially, it does not work: I get "error: module not found: javafx.controls"
I'm not entirely sure why I'd use javafx.controls as my application does not
use that, but not finding javafx.controls seems to be unrelated to lack of use,
which is also borne out by the fact that the compile fails immediately rather
than churning out dozens of errors as it tries to compile things.
