Increase Block Strength in NMS Code for 1.18.1

Hi,
I'm trying to build a plugin where i can increase the block strength of all iron blocks within my world( Server is on 1.18.1). I was able to get a ton of help from previous threads and discussions as to how to go abouts doing this, but I am still Stumbling upon some errors. Here is my code:

Code:

import net.minecraft.world.level.block.Block;import org.bukkit.Material;
import org.bukkit.craftbukkit.v1_18_R1.util.CraftMagicNumbers;
import java.lang.reflect.Field;

import org.bukkit.plugin.java.JavaPlugin;


@Override
public void onEnable() {
// Plugin startup logic
Material iron = Material.IRON_BLOCK;
setBlockStrength(iron,20f);
}


public void setBlockStrength(Material material, float strength) {
try {
Field field=Block.class.getDeclaredField("strength");
field.setAccessible(true);
field.setFloat(CraftMagicNumbers.getBlock(material), strength);
} catch (NoSuchFieldException | IllegalAccessException exception) {
exception.printStackTrace();}
}

The error says that when the getDeclaredField method is called, there is no field called "strength". The java class does not seem to have this parameter. Am I using the wrong block class?


I have seen in various threads using
import net.minecraft.server.v1_18_R0.1.Block instead of
import net.minecraft.world.level.block.Block;
But I am unable to even import the net.minecraft.server.v1_18_R0.1 class (maybe because I didn't get my buildTools correct due to the upgrades after 1.17? But i checked this).

Any thoughts as to how to get this error resolved would be greatly appreciated!
