Following the steps outlined in every tutorial I've found (recompile.bat before reobfuscate.bat), I cannot get my mod to reobfuscate. Everytime I try, it pops this message up in the cmd window: http://pastebin.com/asp8AL7w

 

I'd appreciate any help I can get.

Run as admin? Make sure all instances of Minecraft/Eclipse are closed

Just did both and it gave me the same message.

Stupid question did you make sure you saved it? And is the mods highs folder in side of the minecraft fielder in the eclipse folder?

I did save it. I'm not sure what you mean by the mod's highs, though.

I've run it as an admin, I've recoded the entire mod, yet I'm still getting the same error.

 

My mod is in the Minecraft folder in the src folder.

 

Is there anything I should try doing that I haven't done yet?

It works fine when I'm running it through Eclipse. It's only when I try to recompile and reobfuscate that I get the error.

The exact same thing happens to me. For further information I run it in a Windows Server 2008 64 bits (due to a little inconvinience with my actual computer) using java 64 bits and eclips. And yes I'm pretty sure that both Minecraft and Eclipse are closed.  Thank you.

I figured out a hacky way to get it to work (for me, at the very least).

 

After running recompile.bat and reobfuscate.bat, look for a folder called temp. Inside the temp folder, you will see a jar called client_reobf. If you open that up with 7-zip or WinRAR and pull out the folders that contain your code (starting with the uppermost folder of your package, so for me, "conventnunnery"). After pulling out that top folder, put your texture files in and then zip it up. You should be good to go.

Wow thanks! It worked 

 

Though I would like to know why that happens
