Я пытаюсь загрузить основной класс моего «InventoryModule» с помощью моего модуля-ядра.

Каждый раз, когда я пытаюсь загрузить основной класс, который я успешно прочитал из информационного файла из jar модуля, отображается ClassNotFoundException, и поэтому модуль не загружается.

Вот как я пытаюсь найти и загрузить основной класс (единственное, что есть в классе LobbyModuleConfig — это путь к основному классу)

     @SneakyThrows
    private Optional<Class<?>> loadClass(JarFile file) {
        JarEntry entry = file.getJarEntry("module.json");
        @Cleanup BufferedReader reader = new BufferedReader(new InputStreamReader(file.getInputStream(entry)));

        LobbyModuleConfig config = LobbyCore.instance().gson().fromJson(reader, LobbyModuleConfig.class);

        file.close();

        return Optional.ofNullable(Class.forName(config.mainClass()));
    }
 

Это исключение : (
