Error decompiling with Forge. RenderGlobal, Object -> EntityFX

[bbqroast]

So, I'm trying to decompile with Forge (something I have done successfully before!). This error is persistently popping up though. I'm using a clean jar (I deleted my .minecraft and redownloaded everything using the vanilla launcher), with a clean server jar fresh off minecraft.net. Yet I get this error persistently:

The error seems to be fatal and the install does not finish.

This is what I did:

Downloaded MCP.

Downloaded Forge source (latest version).

Decompressed MCP, put the "forge" folder in with it.

Downloaded a clean Minecraft JAR and a minecraft_server JAR.

Placed the bin/ and minecraft_server.jar in the "jars" folder for MCP.

Ran the "install.bat" script.

It gets to "Recompiling Client" before crashing. I noticed a big list of warnings in another error log for missing fields but I assumed this was the normal "chatter" you get when running programs.

I'm running on Windows 7 64bit with the Java 7 JDK. And my existing Forge based mods (but for 1.2.5 mind you) are still compiling fine.

That's the odd thing. These aren't modified jars. They're both fresh. The client jar was obtained by deleting my .minecraft and opening Mojang's launcher. The server jar was obtained directly off minecraft.net/download.jsp.

Exams are over now. Really want to get into some modding. So is there any fix for this issue?

[LexManos]

There is nothing to fix, you're gunna have to figure out what you're doing wrong that makes them modified jars.

[bbqroast]

Look, I look in the jar, it has a META-INF. I run the forge installer and then it fails to decompile and the META-INF is gone from the jar. Surely this must be something playing up? Or am I doing something wrong.

[keepcalm]

Try installing normal forge on the jar. See what happens.

Hi,

Seeing this and pretty sure I know the answer, I gotta say something.

The jars should be 1.4.4 or you could use 1.4.5.

Be SURE to use MCP 7.22. I bet that's the problem.

If you had MCP update itself, then redownload the right version.
