[1.7.10 - 10.13.1.1217] Mod working fine in eclipse and crashing in launcher

[Christofmeg]

Okay I'm trying to create a block. When I'm running the mod in eclipse everything works fine, but the mod is crashing when I'm testing it with the vanilla minecraft launcher.

 

The numbers on the side is the line numers.

 

Here is a part of the main class nationalscience:

67      @EventHandler
68      public void PreInitialize(FMLPreInitializationEvent event)
69      {
70         NSBlocks.init();
71      }

 

Here is a part of the NSBlocks class:

21      public final class NSBlocks 
22      {
23         public static Block CompressedCobble;
24
25         public static void init() 
26         {
27            CompressedCobble = new BlockCompressedCobble().setBlockName("compressedcobble");
28            GameRegistry.registerBlock(CompressedCobble, ItemCompressedCobble.class, CompressedCobble.getUnlocalizedName().substring(5));
29         }
30      }

 

Here is a part of the BlockCompressedCobble class:

22      public class BlockCompressedCobble extends Block 
23      {
24         public BlockCompressedCobble() 
25         {
26            super(Material.rock);
27            this.setHardness(3.0F);
28            this.setResistance(5.0F);
29            this.setCreativeTab(CreativeTabs.tabBlock);
30         }
31      }

 

Here is the crashreport:

[Bedrock_Miner]

Ok, the problem is that MC cant find the field Material.rock. This is because Minecraft is obfuscated, the field is named something like field_085468_a or so.

How did you compile your mod? Forge gradle normally does the obfuscation for you, or did this build fail for some reason?
