Make import into eclipse work

[effad]

cf. https://github.com/eclipse/buildship/issues/658 and the workaround described there. Maybe this can help and I don't need to remove module-info.java anytime I want to import the project into eclipse.

The above workaround works insofar as there are no compile errors anymore in the src/main/validatorfx folder. But in src/test/java no JavaFX seems to be known at all...

Playing around with org.javamodularity.moduleplugin:

compileTestJava {
	moduleOptions {
		compileOnClasspath = false
	}
}

let's compilation of tests fail on the command line as well...
