Pessoal, iniciei o tutorial da Oracle “Get Started with JavaFX” com o Eclipse, porém estou com um problema que não consigo resolver. O programa lança a seguinte exceção:
[color=red]Exception in thread “main”[/color] [color=blue]java.lang.IllegalArgumentException[/color]: [color=red]expected file name as argument
at com.sun.javafx.css.parser.Css2Bin.main([/color][color=blue]Css2Bin.java:44[/color][color=red])[/color]
Segue o código!
