Here is a copy of my achievement class:

 

 

 

package com.BlackMage.BluTech.Registry;

import net.minecraft.item.ItemStack;
import net.minecraft.stats.Achievement;

/*
* A class that can manage and register BluTech Achievements to Minecraft
*/
public class BluTechAchievements {		
/*
 * Achievement fields - If you are going to add a block, then you need to make sure this class has a public static final 
 *                      field of the Achievement to be added.
 *                
 * Example            - If you are adding an achievement, then you need to create a static field like the following
 * 
 *                          public static final Achievement aquireBluStone = new Achievement(...);
 *                
 *                      See below for the current implementation if you are having problems.
 *                      
 * PLEASE try to keep Achievements in alphabetical order by field name!
 */
// FIXME: Achievements aren't working quite right (textures), it's probably in the constructors
public static final Achievement aquireBluStone  =  new Achievement("achievement.AquireBluStone", "AquireBluStone", 0, 0, BluTechItemMaterials.bluStoneDust, null).setIndependent();

public static final Achievement aquireCarbon    =  new Achievement("achievement.AquireCarbon",   "AquireCarbon",  -2, 0, BluTechItemMaterials.carbonChunk,  null).setIndependent();

public static final Achievement aquireLithium   =  new Achievement("achievement.AquireLithium",  "AquireLithium",  2, 0, BluTechItemMaterials.lithiumChunk, null).setIndependent();

public static final Achievement craftHammer     =  new Achievement("achievement.CraftHammer",    "CraftHammer",    1, 2, BluTechItemMaterials.bluStoneDust, null).setIndependent();


/*
 * Registering Achievements - If you are adding an achievement, then you will need to make sure that this function registers it into
 *                            the game. For ease of use, the RegisterHelper class comes in real handy for this operation.
 *                            All you have to do is add the static field of the achievement that you created, to the array
 *                            being passed into the registerAchievements method in RegisterHelper.
 *                            
 * PLEASE try to keep additions in alphabetical order by field name!
 */
public static void registerAchievements() {

	RegisterHelper.registerAchievements(
		new Achievement[] {
				aquireBluStone,
				aquireCarbon,
				aquireLithium,
				craftHammer
	});
}
}

 

 

 

For some reason since the update the achievments have been erroring and i can not figure out why

The method setIndependent() is undefined for the type Achievement

 

So if that is no longer defined and i can not figure what replaced it
