Jigsaw Structure (i need help pls)

[MrScautHD]

hi, i have tryed to generate a jigsaw Structue but my problem is when i try to regist it make it many Errors (have any a idea how can i register this code?)

this is my code:

public class AlienVillageStructure extends Structure<NoFeatureConfig> {
	private static Feature<NoFeatureConfig> feature = null;
	private static ConfiguredFeature<?, ?> configuredFeature = null;
	public AlienVillageStructure(Codec<NoFeatureConfig> codec) {
		super(codec);
		//MinecraftForge.EVENT_BUS.register(this);
		System.out.println("its works!");
	}

	/**
	 * This is how the worldgen code knows what to call when it
	 * is time to create the pieces of the structure for generation.
	 */
	@Override
	public  IStartFactory<NoFeatureConfig> getStartFactory() {
		return AlienVillageStructure.Start::new;
	}


	/**
	 * Generation stage for when to generate the structure. there are 10 stages you can pick from!
	 * This surface structure stage places the structure before plants and ores are generated.
	 */
	@Override
	public GenerationStage.Decoration getDecorationStage() {
		return GenerationStage.Decoration.SURFACE_STRUCTURES;
	}


	/**
	 * || ONLY WORKS IN FORGE 34.1.12+ ||
	 *
	 * This method allows us to have mobs that spawn naturally over time in our structure.
	 * No other mobs will spawn in the structure of the same entity classification.
	 * The reason you want to match the classifications is so that your structure's mob
	 * will contribute to that classification's cap. Otherwise, it may cause a runaway
	 * spawning of the mob that will never stop.
	 *
	 * NOTE: getDefaultSpawnList is for monsters only and getDefaultCreatureSpawnList is
	 *       for creatures only. If you want to add entities of another classification,
	 *       use the StructureSpawnListGatherEvent to add water_creatures, water_ambient,
	 *       ambient, or misc mobs. Use that event to add/remove mobs from structures
	 *       that are not your own.
	 */
	private static final List<MobSpawnInfo.Spawners> STRUCTURE_MONSTERS = ImmutableList.of(
			new MobSpawnInfo.Spawners(EntityType.ILLUSIONER, 100, 4, 9),
			new MobSpawnInfo.Spawners(EntityType.VINDICATOR, 100, 4, 9)
	);
	@Override
	public List<MobSpawnInfo.Spawners> getDefaultSpawnList() {
		return STRUCTURE_MONSTERS;

	/*
	 * This is where extra checks can be done to determine if the structure can spawn here.
	 * This only needs to be overridden if you're adding additional spawn conditions.
	 *
	 * Notice how the biome is also passed in. Though, you are not going to
	 * do any biome checking here as you should've added this structure to
	 * the biomes you wanted already with the biome load event.
	 *
	 * Basically, this method is used for determining if the land is at a suitable height,
	 * if certain other structures are too close or not, or some other restrictive condition.
	 *
	 * For example, Pillager Outposts added a check to make sure it cannot spawn within 10 chunk of a Village.
	 * (Bedrock Edition seems to not have the same check)
	 *
	 *
	 * Also, please for the love of god, do not do dimension checking here. If you do and
	 * another mod's dimension is trying to spawn your structure, the locate
	 * command will make minecraft hang forever and break the game.
	 *
	 * Instead, use the addDimensionalSpacing method in StructureTutorialMain class.
	 * If you check for the dimension there and do not add your structure's
	 * spacing into the chunk generator, the structure will not spawn in that dimension!

			// only 1 of that piece exists, etc. But you do not have access to the piece's blocks as this list
			// holds just the piece's size and positions. Blocks will be placed later in JigsawManager.
			//
			// In this case, we do `piece.offset` to raise pieces up by 1 block so that the house is not right on
			// the surface of water or sunken into land a bit.
			//
			// Then we extend the bounding box down by 1 by doing `piece.getBoundingBox().minY` which will cause the
			// land formed around the structure to be lowered and not cover the doorstep. You can raise the bounding
			// box to force the structure to be buried as well. This bounding box stuff with land is only for structures
			// that you added to Structure.field_236384_t_ field handles adding land around the base of structures.
			//
			// By lifting the house up by 1 and lowering the bounding box, the land at bottom of house will now be
			// flush with the surrounding terrain without blocking off the doorstep.

i hope any can help me

What is the problem when run ?
