java.lang.NoSuchFieldError: iron [MC 1.7.2][Forge 10.0.1024]

[kris91268]

I am having the following problem with my mod.

 

When I launch it, I get the following error:

java.lang.NoSuchFieldError: iron
at at kris91268.lbd.Blocks.BlockLightBridgeSource.<init>(BlockLightBridgeSource.java:37)
...rest ommited...

 

This only appears to happen when launching my mod with the normal Minecraft launcher; it does not happen in my mod development environment (ForgeGradle)

 

Snippet of BlockLightBridgeSource.java where the error comes from:

public BlockLightBridgeSource()
{
	super(Material.iron); // this is where the error originates.
	setHardness(1.5F);
	setResistance(6.0F);
	setStepSound(Block.soundTypeMetal);
	setBlockName("lightBridgeSource");
	setBlockTextureName("lbd:lightBridgeSource");
	setCreativeTab(CreativeTabs.tabRedstone);
}

 

Any help is much appreciated!

How do you export your mod?

[kris91268]

From what I have seen, it appears to compile automatically. My compiled files are in the bin folder where my ForgeGradle workspace is set up. Is this way not the correct way to do this?

[ruabmbua]

No! What The bin folder contains, are the deobfuscated Files of your mod. You have to run gradlew.bat build to get working obfuscated.class files. The process converts all fields, methods and types into obfuscated ones. If you run the command you get a working mod jar in build/libs.

Thank you, that helped lots. It now works fine without that error.
