Mod code not working after one change

While creating my mod I've noticed that the bricks block I've created can be mined by hand despite setting the harevsting tool to a pickaxe. After looking for a solution for a while I found it, and changed part of the block code from

public static class CustomBlock extends Block {
        public CustomBlock() {
            super(Block.Properties.create(Material.ROCK).sound(SoundType.STONE).hardnessAndResistance(2f, 6f).setLightLevel(s -> 0).harvestLevel(1)
                    .harvestTool(ToolType.PICKAXE));
            setRegistryName("mossy_bricks");
        }

to

public static class CustomBlock extends Block {
        public CustomBlock() {
            super(Block.Properties.create(Material.ROCK).sound(SoundType.STONE).hardnessAndResistance(2f, 6f).setRequiresTool(ToolType.PICKAXE).setLightLevel(s -> 0).harvestLevel(1)
                    .harvestTool(ToolType.PICKAXE));
            setRegistryName("mossy_bricks");
        }

And it stopped working. All I've added is the .setRequiresTool property. Any idea what causes this?
Also the only error on the console I see is error: method setRequiresTool in class Properties cannot be applied to given types;
