I am trying to make my first spigot plugin but it is not loading can anybody help?

package me.inekadam.firstplugin;

import org.bukkit.plugin.java.JavaPlugin;

public final class Firstplugin extends JavaPlugin {

    @Override
    public void onEnable() {
        // Plugin startup logic
        System.out.println("Plugin is loaded");
    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
    }
}

I was expecting it to load.
