Using ModiTect to generate module info and create runtime image

Tried to use JLink to create a runtime image, however:

Error: automatic module cannot be used with JLink: graphviz.java

I'm using the following library which has only automatic modules.

Did some searches, and it seems that I can use ModiTect to generate module-info for the library and create a runtime image.

However, as I am new to modules I couldn't figure it out.
I guess I would need a more in-depth explanation then what I could find on ModiTect's GitHub page.

my modules-info.java:

module elitonlais {
    requires javafx.controls;
    requires javafx.fxml;
    requires graphviz.java;

    opens elitonlais to javafx.fxml;
    opens elitonlais.controller to javafx.fxml;
    opens elitonlais.model to javafx.fxml;

    exports elitonlais;
    exports elitonlais.controller;
    exports elitonlais.model;
}

You should be able to add it following the documentation at the link Adding module descriptors to existing JAR files.

Adding the following to your existing pom.xml as an additional <execution> step for ModiTect should work:

                    <moduleInfoSource>
                        module guru.nidi.graphviz {
                            requires ...;
                            exports ...;
                            provides ...
                                with ...;
                        }
                    </moduleInfoSource>
                    <!-- or use moduleInfoFile instead of the above -->
                </module>
                <module>
                    ...
                </module>
            </modules>
        </configuration>
    </execution>
</executions>

Note also that the project has specified an automatic module name of guru.nidi.graphviz so you'll need to change your own module-info to require that, rather than the auto-derived graphviz.java.
