I'm trying to run the install file inside the Forge folder of MinecraftForge.src so that I can actually start learning to mod Minecraft, but am getting a Client Recompile error. I am using MCP726a, jdk-7-windows-x64, and minecraftforge-src-1.4.7-6.6.1.523.

 

Here is the full error:

==================

Client recompile failed, correct source then rerun updatemd5

Hi!

 

The source, as inn your own code is not correct.

The error you are receiving says: "deprecation" which means the method(s) you are trying to use have been marked as deprecated, meaning they are removed and won't work. This is meant to be an warning to let you know that you are using outdated methods and need to change them into whatever the new way of doing things is.

 

In the process of authoring computer software, its standards or documentation, or other technical standards, deprecation is a status applied to features, characteristics, or practices to indicate that they should be avoided, typically because they have been superseded.

 

 

 

Except it's not my code? I am trying to set Forge up so I can open it in eclipse so I can start modding. As far as I'm aware I'm doing everything correctly to set forge up, but I get that error.

Oh I see, I'm terribly sorry, my mistake!

 

If you try and extract minecraftforge-src-1.4.7-6.6.1.523. anywhere you want to and then just run the install file, what happens?

Normal forge will fix everything for you, including downloading relevant files such as MCP and the client, so what happens when you try to just run the install file? Does it download the mcp files etc.?

I tried that, I'm still getting the same error. That said, the code depreciation makes me think I'm using the wrong version of SDK, and that I should downgrade. Could this be the case? I'm currently using the latest version of JDK, 7u13 x64, for windows.

I figured it out, thanks for the help though! Apparently the installer doesn't like the 64 bit JDK. I changed to 86x JDK and it installed fine.
