Commands

Create a command class and implements the com.xg7plugins.commands.setup.Command class

Then create a command like this:

package org.example;

import com.xg7plugins.XG7Plugins;
import com.xg7plugins.commands.node.CommandConfig;
import com.xg7plugins.commands.setup.Command;
import com.xg7plugins.commands.setup.CommandSetup;
import com.xg7plugins.commands.utils.CommandArgs;
import com.xg7plugins.commands.utils.CommandState;
import org.bukkit.command.CommandSender;

@CommandSetup(
        name = "example",
        description = "An example command",
        syntax = "/example",
        permission = "myextension.command.example",
        pluginClass = XG7Plugins.class,
        iconMaterial = XMaterial.DIAMOND
)
public class ExampleCommand implements Command {
    
    @CommandConfig
    public CommandState executeRoot(CommandSender sender, CommandArgs args) {
        sender.sendMessage("This is an example command!");
        sender.sendMessage("ARGS: " + args.toString());
        return CommandState.FINE;
    }
    
    //IF you want to add subcommands, you can do it like this:
    
    @CommandConfig(
            name = "sub",
            description = "An example subcommand",
            syntax = "/example sub",
            permission = "myextension.command.example.sub",
            iconMaterial = XMaterial.EMERALD
    )
    public CommandState sub(CommandSender sender) {
        sender.sendMessage("This is an example subcommand!");
        return CommandState.FINE;
    }    
}

Then, register the command in getCommands() method on Main class

@Override
public List<Command> getCommands() {
    List<Command> commands = new ArrayList<>();
    commands.add(new ExampleCommand());
    return commands;
}

Done!
