[1.7.2] Cannot find symbol : variable Items

[Someone Else 37]

I'm running a clean install of Forge 1.7.2-10.12.1.1061 and the associated ForgeGradle on Ubuntu 12.04, and am NOT using Eclipse or any other IDE, if that matters.

 

Anyway, I am unable to do anything with any vanilla items because the compiler doesn't recognize the identifier "Items" and crashes. Blocks are fine, as are things based on the ore dictionary, but I can't use any items in things like crafting recipes.

 

Here's the error spat out by the compiler shortly after Gradle prints out ":compileJava":

~/Games/Minecraft/MCP/mc172/forge1061/build/sources/java/se37/triangulum/Triangulum.java:65: cannot find symbol
symbol  : variable Items
location: class se37.triangulum.Triangulum
GameRegistry.addRecipe(ironTri, " s ", "   ", "s s", 's', new ItemStack(Items.iron_ingot));
                                                                        ^
1 error

 

And here's the entire base class for my mod:

 

package se37.triangulum;

@Mod(modid = Triangulum.MODID, version = Triangulum.VERSION)
public class Triangulum
{
    public static final String MODID = "triangulum";
    public static final String VERSION = "0.0.0";

    public static Item triangleWood;
    public static Item triangleIron;
    public static Item triangleGold;
    public static Item triangleDiamond;
    
    @EventHandler
    public void preInit(FMLPreInitializationEvent preInitEvent) {
triangleWood = new Triangle().setUnlocalizedName("triangleWood").setTextureName("triangulum:triangleWood");
GameRegistry.registerItem(triangleWood, triangleWood.getUnlocalizedName());
triangleIron = new Triangle().setUnlocalizedName("triangleIron").setTextureName("triangulum:triangleIron");
GameRegistry.registerItem(triangleIron, triangleIron.getUnlocalizedName());
triangleGold = new Triangle().setUnlocalizedName("triangleGold").setTextureName("triangulum:triangleGold");
GameRegistry.registerItem(triangleGold, triangleGold.getUnlocalizedName());
triangleDiamond = new Triangle().setUnlocalizedName("triangleDiamond").setTextureName("triangulum:triangleDiamond");
GameRegistry.registerItem(triangleDiamond, triangleDiamond.getUnlocalizedName());
    };

    @EventHandler
    public void init(FMLInitializationEvent event) {
ItemStack woodTri = new ItemStack(Triangulum.triangleWood);
ItemStack ironTri = new ItemStack(Triangulum.triangleIron);
ItemStack goldTri = new ItemStack(Triangulum.triangleGold);
ItemStack diamTri = new ItemStack(Triangulum.triangleDiamond);

GameRegistry.addRecipe(new ShapedOreRecipe(woodTri, " s ", "   ", "s s", 's', "stickWood"));
GameRegistry.addRecipe(ironTri, " s ", "   ", "s s", 's', new ItemStack(Items.iron_ingot));
    };
}

 

Yes, I realize that I don't need half those imports, I'm just too lazy to go back and remove the ones I don't need because I might need them later.

 

If I comment out that last line, everything works fine, except I can't craft the item.

 

Note that the compiler fails upon reaching the "Items" thing, NOT the "iron_ingot" part. I've tried "Items.ingotIron", "Item.iron_ingot", "Item.ingotIron", even trying an ore dictionary recipe with "ironIngot" or "ingotIron" (both of which compiled, but didn't let me craft the item) and importing net.minecraft.item.Items, no dice.

 

My question is this: Am I just doing something wrong, or is this actually a Forge bug? And if it is a bug, is there any other workaround?

 

Also, where can I find a list of the internal names of all the vanilla items and blocks and things, or do I just have to blindly guess things like "Blocks.blockIron", "Blocks.ironBlock", and "Blocks.iron_block" until something works?
