    I have a problem to save the blockstate to config and load them when a player place/break a spawner
    I want to create the same spawner with the saved blockstates when a player break it with a silk pick
    Code:
    @EventHandler
    public void onSpawnerBreak(BlockBreakEvent e) {
        Block b = e.getBlock();
        Player p = e.getPlayer();
        if (b.getType() == Material.MOB_SPAWNER) {
            ItemStack hand = p.getItemInHand();
            if (hand.containsEnchantment(Enchantment.SILK_TOUCH)) {
                e.setCancelled(true);
                b.setType(Material.AIR);
                Location l = b.getLocation();
                double ax = l.getX();
                DecimalFormat xf = new DecimalFormat("0");
                String x = xf.format(ax).replaceAll("-", "");

                double ay = l.getY();
                DecimalFormat yf = new DecimalFormat("0");
                String y = yf.format(ay).replaceAll("-", "");

                double az = l.getZ();
                DecimalFormat zf = new DecimalFormat("0");
                String z = zf.format(az).replaceAll("-", "");
                int level = SpawnersFile.getSpawners().getInt("spawners." + x + y + z + ".Level");
                String ent = SpawnersFile.getSpawners().getString("spawners." + x + y + z + ".Mob");
                int delay = SpawnersFile.getSpawners().getInt("spawners." + x + y + z + ".Delay");
                int mindelay = SpawnersFile.getSpawners().getInt("spawners." + x + y + z + ".MinDelay");
                int maxdelay = SpawnersFile.getSpawners().getInt("spawners." + x + y + z + ".MaxDelay");
                int amount = SpawnersFile.getSpawners().getInt("spawners." + x + y + z + ".Spawn-Amount");
                    ItemStack spawner = new ItemStack(Material.MOB_SPAWNER);
                    ItemMeta spawnerMeta = spawner.getItemMeta();
                    BlockState blockState = e.getBlock().getState();
                    CreatureSpawner s = ((CreatureSpawner) blockState);
                    s.setSpawnedType(EntityType.valueOf(ent));
                    s.setDelay(delay);
                    s.setMinSpawnDelay(mindelay);
                    s.setMaxSpawnDelay(maxdelay);
                    s.setSpawnCount(amount);
                    s.update();
                    spawnerMeta.setDisplayName(SpawnerCheck.SpawnerName(b));
                    String lore = Main.color("&9Livello: " + String.valueOf(level));

                    SpawnersFile.saveSpawnersFile();
            }

    "org.bukkit.craftbukkit.v1_12_R1.inventory.CraftMetaBlockState cannot be cast to org.bukkit.block.CreatureSpawner"

    Seems like you imported the wrong BlockState

    Anyway. If the error says wrong class somehow you use the craftbukkit BlockState and not the bukkit one. It's on you to look up your code and find out how this happens.

    So probably I use the wrong API?
