I'm getting this error on compile time and I have no idea why. The error log doesn't shed much light on it either. Already searched for other answers, they all pertain to frameworks that I'm not using or recommend to make sure the name of the file is the same as the name of the class(yup, both named "FolderSyncer4"). Code for reference:
FolderSyncer4.java
package sample;

public class FolderSyncer4 extends Application {
final String FOLDER_SYNCER = "FolderSyncer";
Stage theStage;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
theStage = primaryStage;
//TODO do the FXML stuff, hope this works
//Parent root = FXMLLoader.load(getClass().getResource("FolderSyncerMainWindow.fxml"));
//Display the "Selecting" scene at first
theStage.setTitle(FOLDER_SYNCER);
theStage.show();
}
}

java -jar xxx.jar sample.FolderSyncer4 should work. It seems you use sample.Main instead.
