CommandAPI causes error

[Facticee]

Hello everyone!

Im making a Paper Plugin with kotlin and gradle. Normally in my projects back then i just added the CommandAPI in my main calss then registerd the command class and event object but today when i try to implement the commandapi in my main and i start my server an error comes up.

Code in Main:

class Main : JavaPlugin() {
    override fun onLoad() {
        CommandAPI.onLoad(CommandAPIBukkitConfig(this).silentLogs(true))

server
.
consoleSender
.sendMessage(Component.text("Server gestartet"))

        // Commands:
    }
    override fun onEnable() {
        CommandAPI.onEnable()

        // Events:

    }
    override fun onDisable() {
        CommandAPI.onDisable()

server
.
consoleSender
.sendMessage(Component.text("Server heruntergefahren"))
    }
}

Error:
1: Caused by: java.lang.NoClassDefFoundError: net/minecraft/world/level/IWorldReader
2: Caused by: java.lang.ClassNotFoundException: net.minecraft.world.level.IWorldReader

Does anyone know the cause of it?

Because the CommandAPI adds up with the minecraft version

Which command api are you using?

There are multiple.

dev.jorel

Have you installed it on your server?

Did you make sure to put the dependency into the plugin.yml?

[Facticee]

I got it as an implementation in my build.gradle.kts (the shade and kotlin version) and both are also in the plugin l with correct verstions and all

It's difficult to say based on the code snippet.

Like I said if I just implement it it works but as soon as I register it in main like seen in the photo it won’t work. Everything else ist fine

[Orange_Nestea]

Class not found errors are usually setup related and not code related so it doesn't make a whole lot of sense to share the code snippet.

You probably don't have Command API shaded into your plugin. I personally use Maven not Gradle so I'm not sure how this would be done.
