SkriptJava

Run Java plugins without compiling them!

Usage
Under plugins/SkriptJava, you can put your .java files to run when the server is up and loaded. This plugin will compile them at runtime and execute them.
NOTE: YOU HAVE TO BE USING A SUITABLE JDK JAVA VERSION INSTEAD OF JRE WHEN RUNNING THE SERVER!!!!!!!!!!!!!!!!!!!!!!!!!

Execution
Each script has to have a load() and unload() function, as well as a constructor that takes in the Plugin parameter. There is a demo script loaded for you to see when the plugin loads for the first time.

Listeners
You can call Bukkit functions and classes like normal. You can also implement Listener and annotate methods with EventHandler if you want to handle events. It's the same as you would do for a plugin.

Commands
You can also make command scripts by implementing CommandExecutor and having a getCommand() function that returns the command name.

Example
HelloWorld.java

package skriptjava;

/**
* You can use Bukkit imports here. It would still work.
*/
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;
import org.bukkit.plugin.Plugin;

import java.util.HashSet;
import java.util.UUID;

/**
* A basic Java class, with a Bukkit Listener implemented to handle events.
*/
public class HelloWorld implements Listener, CommandExecutor {

    private HashSet<UUID> uuids;
    private final Plugin skriptJava;
    public HelloWorld(Plugin plugin) {
        this.skriptJava = plugin;
        uuids = new HashSet<>();
    }

    /**
     * Every script must start with a load method. This will be called when a script is loaded.
     */
    public void load() {
        System.out.println("Hello World! This is a Demo Java Skript");
        skriptJava.getServer().getScheduler().runTaskTimer(skriptJava, () -> {
            for (Player player : Bukkit.getOnlinePlayers()) {
                player.sendMessage("You can even run scheduled scripts!");
            }
        }, 0L, 20L);
    }

    /**
     * Every script can also have an unload method. This will be called when unloading the script,
     * and its better memory management. It is not necessary but it is recommended.
     */
    public void unload() {
        uuids.clear();
    }

    /**
     * You can handle events here by using normal @EventHandler annotations.
     */
    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        uuids.add(e.getPlayer().getUniqueId());
        broadcast(e.getPlayer().getUniqueId(), e.getPlayer().getName());
    }

    @EventHandler
    public void onLeave(PlayerQuitEvent e) {
        uuids.remove(e.getPlayer().getUniqueId());
        broadcast(e.getPlayer().getUniqueId(), e.getPlayer().getName());
    }

    private void broadcast(UUID uuid, String name) {
        for (Player player : Bukkit.getOnlinePlayers()) {
            player.sendMessage(name + " (" + uuid + ") has joined the server!");
        }
    }

    /**
     * Handle commands using Bukkit CommandExecutor interface.
     */
    @Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        commandSender.sendMessage("This is a Demo Java Skript command!");
        return false;
    }

    /**
     * Running /demo will execute the onCommand method.
     */
    public String getCommand() {
        return "demo";
    }
}
