To answer directly, `-PX` defines a [project
property](https://docs.gradle.org/current/userguide/build_environment.html#sec:project_properties)
`X`. For it to be useful, it needs to be read with `project.findProperty("X")`
(or `providers.gradleProperty`). In the main build it is not done so;
`JDK_HOME` is read directly from the environment variables:
def envJavaHome = cygpath(System.getenv("JDK_HOME"))
If you want to override it in the CLI, you either need to set it there or we
need to add manual reading for it. Since `JDK_HOME` is used for JavaFX only, is
there a particular reason you need to override it in the CLI?
I have a branch that organizes the various versions variables to something that
is more easily understood. I'll see if it makes sense to merge it before this
change when reviewers get to this.
