NoClassDefError on YamlConfiguration

[orchid karma]

For some reason I keep getting a NoClassDef error on YamlConfiguration. Any ideas appreciated. It’s a waterfall plugin if that changes anything. LMK if more code needed

Error:

java.lang.NoClassDefFoundError: org/bukkit/configuration/file/YamlConfiguration
    at me.alfiejay.altcontrol.datafiles.YamlFile.<init>(YamlFile.java:23) ~[?:?]

Relevant code: (In abstract class)

    /**
     * Loads Yaml file data
     * @param fileName Name of file in resources (include the .yml)
     * @param plugin Plugin instance
     */
    public YamlFile(String fileName, Plugin plugin) {
        if (!plugin.getDataFolder().exists()) plugin.getDataFolder().mkdir();
        file = new File(plugin.getDataFolder(), fileName);
        if (!file.exists()) createFile();
        config = YamlConfiguration.loadConfiguration(file);
    }

Wrong import

Waterfall is basically a Bungee clone?

[orchid karma]

Yh

Waterfall is like the PaperMC of bungee

[glacial egret]

then you need the non Bukkit import for YamlConfiguration

[orchid karma]

Oh right. IDE only offered Bukkit so IG I need to find what dependency it's from

[glacial egret]

you need teh md5 one. or whatever Waterfall names it

[orchid karma]

Right thank you :D
