Hi,

When trying to use the Minecraft Coder Pack with Forge, I have this error:

I have searched Google, Forge fourms, and other places for help.  I have asked other friend's in modding for help, they have not been able to.  I have only had this problem after switching computers, and I am not able to use another now though.  I am not sure if this is the right form for this, since it relates to the programming, though not the code.

 

I am using mcp751 for 1.5.2 and minecraftforge-src-1.5.2-7.0.8.703

Sorry for pasting the CMD log, there is no forge log. I have looked a lot for it, since this is a fairly unused computer there is not many files to search through.

 

Oh, and using Windows 7 Home 64-bit.

 

Any help would be great, thanks.

You're not using Forge's install script, wipe out your MCP folder and do so. It'll setup everything for you.

I've been getting the same problem ClassNotFound qv ive always used the forge installs cript saves me the time to download mcp, but for some reason after the install script has run I can even decompile the code again same error missing classfile qv

 

Used: MCP 1.5.2-7.8.0.715 and also same on MCP 1.5.2-7-8-0-725, used the install script no errors, but can't decompile afterwards so unless something has changed I really have no idea what or why

 

**Edit**

OK got this working the minecraft.jar was almost 1 MB smaller after running the script and finishing the installation. I simply replaced that .jar with the original jar downloaded from the minecraft site added forge to it and it decompiled without problems

-.-

DO NOT run the DECOMPILE script.

The install.cmd will do everything for you.

ClassNotFound gv is caused by you trying to decompile the server, which you DONT NEED TO DO.
