Could it be that your Path isn't right at? Because it looks like the java.lang.NoClassDefFoundError: Stage is saying to you that it could not found the "class" you are looking for and if you have the file, which i guess you have, then it only could be that it seeks at the wrong file

Parent root = FXMLLoader.load(getClass().getResource("mainWindow.fxml"));
