Exception running application sample.Main 

これはあなたのエラーログがCaused by: java.lang.ClassNotFoundException: com.jfoenix.controls.JFXButton言うメインParent home = FXMLLoader.load(getClass().getResource("home.fxml"));

Answer 1

で21行目であるがありますエラーです。これは、クラスが見つかりませんでしたので、fxmlをロードできなかったことを意味します。 jfoenixのライブラリのインポートに問題があると思うか、JFXButtonのインポートをFXMLファイルに含めるのを忘れてしまったと思います。
