Cant run Minecraft test

I added a recipe for an item but now it won't work. I tried deleting it from the workspace, I even tried to delete it from the folder but it just kept coming back. If it helps here is the error

C:\Pylo\MCreator183\forge\build\sources\main\java\mod\mcreator\mcreator_refinedMobBloodRecipe.java:16: error: cannot find symbol
      GameRegistry.addSmelting(new ItemStack(mcreator_mobBlood.block, (int) (1)), new ItemStack(mcreator_refinedMobBlood.block, (int) (1)), 1F);
