Create working .jar out of Maven-Project - JavaFX (Afterburner.fx) Project : Currently stuck with Errormessage

Question

I´ve created a small JavaFx Project with the use of the afterburner.fx framework. It works fine when I start it in the IDE (IntelliJ), but after I created a fat .jar out of it via the "maven-assembly-plugin" it fails to open the Second View.

Pom.xml:

SetupPresenter.onStart():

public void onStart(){
    InProgressView inProgressScreen = new InProgressView();
    Scene scene = new Scene(inProgressScreen.getView());
    window.setScene(scene);
    window.setTitle("Currently Running");
    window.show();

    SetRating app = new SetRating();
    new Thread(app).start();
}

Errormessage:

Caused by: java.lang.IllegalStateException: Cannot load file InProgress.fxml
    at com.airhacks.afterburner.views.FXMLView.getResourceCamelOrLowerCase(FXMLView.java:221)

The same Errormessage you get in the IDE, when you not include the .fxml in the pom.xml as displayed following:

<resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.fxml</include>
                <include>**/*.css</include>
                <include>**/*.properties</include>
                <include>**/*.png</include>
            </includes>
        </resource>

So probably it has something to do with it. But as I said, the First View is loaded and it is initiated in completly the same way as the Second View:

@Override
public void start(Stage stage) {
    window = stage;

    SetupView setupScreen = new SetupView();
    Scene scene = new Scene(setupScreen.getView());
    window.setScene(scene);
    window.setTitle("ScotlandYard");
    window.show();

}

I´ve tried to find the solution by myself today and tried to generate the fat .jar in varoius other ways, but wasnt able to get a running .jar.

Answer 1

I found the Answer

Solution for me was just to rename the .fxml Files to start Uppercase: As an example I renamed view1.fxml to View1.fxml. I guess it has something to do with the way windows is accesing the files inside an jar/zip.
