IntelliJ IDEA GUI builder – no Java code generated

I have designed my GUI form in the IntelliJ IDEA GUI designer, and selected the radio button in Project Settings → GUI Designer to generate source code instead of `.class` files, but my `.java` file with code looks like this: ``` public class PovRayEmptyProjectWizardPanelVisual { private JTextField textField1; private JTextField textField2; private JTextField textField3; private JButton button1; } ``` That’s it – no code creating the GUI was generated. How do I manually trigger such code generation, so that I can compile the resulting `.java` file with Maven?
