Heres the Code and the line where the Error appears.

Original Code (open) Original Code (close)

Code:

    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        this.event = event;
        if(plugin.inJump.contains(event.getPlayer().getName())) {
            Player player = event.getPlayer();


            Block block = (Block) player.getLocation().subtract(0.0D, 1.0D, 0.0D).getBlock();

            if(((org.bukkit.block.Block) block).getType() == Material.GOLD_BLOCK) {
                player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 20*5, 3));
                player.playSound(player.getLocation(), Sound.GHAST_SCREAM, 3, 2);
            }
            if(((org.bukkit.block.Block) block).getType() == Material.BEDROCK) {
                teleportToSpawn(player);
            }
        }
    }

 

Do you mean this one?
Just to make sure

Code:

import jdk.nashorn.internal.ir.Block;

 

Okay just did it and cant export now what do I do with that now?

Code:

            Block block = (Block) player.getLocation().subtract(0.0D, 1.0D, 0.0D).getBlock();

and also:
I get this Error:

Code:

Error:java: invalid source release: 12

 

Oh okay got it it was my fault but now theres this errors:

Code:

Error:(145, 13) java: cannot find symbol
  symbol:   class Block
  location: class classes.Listeners

and

Code:

Error:(145, 28) java: cannot find symbol
  symbol:   class Block
  location: class classes.Listeners

 

The block I had before

Okay it was my fault thank you.

Theres just one last question cause I dont wanna make like hundreds of posts like there no Error but when I get into the Arena my inventory wont get cleared and when I click the sign he wont teleport me to the last loc and wont give me 2 diamonds.

Code:

    @EventHandler
    public void onSignInteract(PlayerInteractEvent event) {
        Player p = event.getPlayer();
        if(plugin.inJump.contains(p.getName())) {
            if(event.getAction() == Action.RIGHT_CLICK_BLOCK) {
                if(event.getClickedBlock().getState() instanceof Sign) {
                    Sign s = (Sign) event.getClickedBlock().getState();

                    if(s.getLine(0).equalsIgnoreCase("§b§oEnojump")) {
                        if(s.getLine(1).equalsIgnoreCase("§4§lZiel")) {

                            plugin.inJump.remove(p.getName());

                            p.getInventory().clear();
                            ItemStack[] old = plugin.oldItems.get(p.getName());
                            p.getInventory().setContents(old);
                            p.updateInventory();

                            Location loc = plugin.oldLoc.get(p.getName());
                            p.teleport(loc);

                            p.sendMessage(plugin.prefix + "§8Du bekommst 2 Diamanten weil du es geschafft hast!");
                            p.getInventory().addItem(new ItemStack(Material.DIAMOND, 2));
                        }
                    }
                }
            }
        }
    }
