[1.16.5] Materials of Blocks not found

[Heinzchen]

I just updated my mod to Forge version 36.2.0 from 36.0.1 and now I get following error for any of Blocks at the Registry after I executed Gradle Task runClient.

Error:

error: cannot find symbol
            BlockList.copper_block = new Block(Block.Properties.create(Material.IRON).hardnessAndResistance(2.0F, 3.0F).sound(SoundType.METAL).harvestLevel(1).harvestTool(ToolType.PICKAXE)).setRegistryName(location("copper_block")),
                                                                                                                               ^
  symbol:   variable IRON
  location: class Material

(same with ROCK instead of IRON)

 

But the Error ist just shown after I executed the Task and not at the code itself. 

P.S. I looked it up: The class Material with the variables IRON and ROCK exists.
