Empty Files created when using Kotlin Classes without "extras-kotlin" module

[xMrAfonso]

I've been using Configurate with Kotlin and encountered some issues. The extras-kotlin module mentions that it adds support for data classes. I assumed this meant normal Kotlin classes would be fully supported out of the box. However, when attempting to create configurations with normal Kotlin classes, the files are created but remain empty with no errors being present on the console.

I'm unsure if this behavior is intended or if I'm missing something in my setup.

Why I'm Not Using extra-kotlin:
I'm not using the extra-kotlin module because it depends on kotlin-reflect, which has known compatibility issues with Paper loaders. Additionally, shading kotlin-reflect properly into my project has been problematic.

Method Used to Create Configurations:
Here’s the method I use to create and load configurations:

private fun <T> create(clazz: Class<T>, fileName: String): T? {
    try {
        Files.createDirectories(dataFolder)

        val path: Path = dataFolder.resolve(fileName)

        val loader: YamlConfigurationLoader = loader(path)
        val node: CommentedConfigurationNode = loader.load()
        val config = node.get(clazz)

        if (!Files.exists(path)) {
            Files.createFile(path)
            node.set(clazz, config)
        }

        loader.save(node)
        return config
    } catch (exception: IOException) {
        exception.printStackTrace()
    }
    return null
}

Possible Cause:
I suspect the issue might be related to the object mapper since Kotlin has its own quirks compared to Java. If that's the case, the documentation should specify that the extra-kotlin module not only supports data classes but also provides full support for normal Kotlin classes.

Expected Behavior:

• Normal Kotlin classes should be supported out of the box without requiring the extra-kotlin module.
• If additional dependencies like kotlin-reflect are mandatory, this should be clarified in the documentation.

Let me know if I’m missing something or if this is unintended behavior.
