Gluon FX: Native Window app fails: no glib-lite in java.library.path

Question

My goal is to create a Windows ".exe" file for my JavaFX Pac-Man game, see https://github.com/armin-reichert/pacman-javafx.

I followed the instructions from the Gluon website https://docs.gluonhq.com/#platforms_windows and installed all the required tools.

UPDATE: After having removed all hyphens from the Maven artifact name and all paths, I am able (after running mvn clean install) to

1. Run the application using mvn gluonfx:run or mvn gluonfx:runagent
2. Build the native Window application with mvn gluonfx:build and mvn gluonfx:package. Not sure if mvn gluonfx:install is needed?

But when I try to run the native application using mvn gluonfx:nativerun, exceptions occur because resources cannot be loaded (fixed).

My application is modular, module name is "de.amr.games.pacman.ui.fx".

The resource files are all in subfolders under "src/main/resources/de/amr/games/pacman/ui/fx".

The application runs from my IDE (Eclipse) or with the gluonfx targets mentioned above, but the native application cannot access the resources (sounds etc.).

UPDATE #2:

To have .mp3 and .wav files loaded successfully, I had to add the following lines to the "resources" block in file src\main\resources\META-INF\native-image\resource-config.json:

  "includes":[
->  {"pattern": ".*\\.mp3$"},
->  {"pattern": ".*\\.wav$"},

But when running the native application, now the following exception occurs:

The problem seems to be the "resource:" URL protocol (getClass().getResource(...) is used in the code). When running mvn gluonfx:runagent, the URLs have a "file:" protocol and sounds are loaded.

Without sound, the application runs fine, so this is the last remaining issue.

UPDATE #3:

If I comment-out the creation of JavaFX AudioClip objects in my code, the native application works fine!

UPDATE #4:

I think this issue is related to: https://github.com/gluonhq/substrate/issues/336

UPDATE #5:

Just found out about the Gluon Attach library and tried it out. Is my impression correct that there does not exist an audio service for platform "Desktop"? So I cannot load audio files from a native Windows app using Gluon Attach?

Thanks for any hints how to solve this issue.
