Running JavaFX-11 applications from within Eclipse fails

[José Pereda]

I've just noticed that this issue happens not only with Maven but also with
Gradle projects (Gradle + Eclipse 2018-09 + Windows with Oracle JDK 1.8),
running gradle tasks from Eclipse.

The same proposed workaround can be applied to the build file:

run {

    systemProperty "java.library.path", "C:\tmp"

}
