[ModernPluginLoadingStrategy] Could not load plugin 'xyz.jar' in folder 'plugins' java.lang.reflect.InvocationTargetException: null #8

Hi! I loved your library and wanted to use it in my plugin (which btw is an addon for DiscordSRV). However, when I tried to run my server, I encountered this error:

Here is my file structure: image And here's the main file:

package me.jedrek0429.discordsrv.nicksynchronization;

// imports

public final class NickSynchronization extends JavaPlugin {

    @Getter private final File configFile = new File(getDataFolder(), "config.yml");
    private final DynamicConfig config;

    public static NickSynchronization getPlugin() {
        return getPlugin(NickSynchronization.class);
    }

    public static DynamicConfig config() {
        return getPlugin().config;
    }

    public NickSynchronization() {
        super();

        getDataFolder().mkdirs();
        config = new DynamicConfig();
        config.addSource(NickSynchronization.class, "config", configFile);
        try {
            config.saveAllDefaults();
        } catch (IOException e) {
            throw new RuntimeException("Failed to save default config files", e);
        }
        try {
            config.loadAll();
        } catch (Exception e) {
            throw new RuntimeException("Failed to load config", e);
        }
    }

    // ...
}

As you can see, my project is rather basic, so I didn't expect any errors. Is this a problem with your library or on my side?

Are you shading the library into your plugin? Open your plugin .jar file in 7zip and see if the class exists in the jar

It does.

Looks like after some changes I managed to get... a different error.

This is my first time using Maven, so I may have overlooked an easy solution. Sorry for bothering you if that's the case.
