I have followed the instructions given for downloading the custom client features, yet I get the error "Warning: lib/minecraft.jar not found". I have minecraft.jar in the lib folder and I have tried re-doing the given instructions three times with no luck. I am using WinRAR, I have Java version 6 update 18 (the latest Java type), I have 27.5 GB free worth of space on my computer, and I am using a Vista. I do realize this is little information, but please ask if you need more specific information and I'll try to find that information.

It seems that run.bat is autodetecting an older version of Java. Be sure that you have the latest version at Java.com. If you do then you need to set a custom Java path in run.bat, right click it and select 'Edit'.
Change:
set JAVA6="auto"
To:
set JAVA6="C:\MyPath\bin\java.exe"
(Change "C:\MyPath" to your actual java installation's path, normally "C:\Program Files\Java\jre6\bin\java.exe")

I am getting the same error as well, exactly as Corruption64 is getting.
| | |
can somebody help us out
| | |
Yeah I get the same thing, Checked through the Java site that I have the latest version installed. Dunno what could be causing this.
 | | |
hmm are you sure you guys are using the last minecraft.jar?
if not it could may ingore it or something
| | |
Not sure, but I downloaded it from the link provided in the download section. I assume it's the link to the latest one since it's on the minecraft.net site. I tried looking around for the jar file to find a newer version but I couldn't find it anywhere else.
| | |
i already changed the path as stated earlier and am getting this:

Maybe a Vista problem since I'm also running Vista.
| | |
Can't be, getting same thing on XP. I google around and it looks like its bad coding on their part. At least that's what it seems like from all the links I found on google.
| | |
try redownloading minecraft.jar
| | |
The problems obviously not with the mminecraft file. If you look at the run.bat file in a text editor it pretty much returns "minecraft.jar not found" or every other error.
It's got to to with the way it's accessing the java files. Maybe it only works for people with older java version? I installed the latest one twice now and I still get the errors.
| | |
Apparently whenever starting a mode my internet connection
was getting corrupt files and causing minecraft not to function
correctly (I know this because multiple computers on my connection had
all the same problems). I went to a friends house and everything loaded
fine. I copied the "www.minecraft.net" Temp folder
(C:\UserName\AppData\Local\Temp\www.minecraft.net (AppData is a hidden
folder)) onto a flash drive and pasted it into my Temp folder and
"ABRAHADABR!!!" it works!
Thanks for the help!
| | |
I'll upload it if u tell me where. I'm still working on getting infdev to work so once that's done ill put the. folder sumwhere as long as that's allowed.

Open up "C:\Users\YOUR USERNAME\AppData\Local\Temp". Remove both 'minecraft.net' and 'www.minecraft.net' folders. Try again.

This is exactly what I get, even after removing those folders:

Yes, I downloaded the stuff about twelve times from different sources.
Yes, I changed the java path from auto.
Using Windows XP.
Can someone present a definite solution to this already? It obviously works for a large number of people.

I made a new folder in lib and named it minecraft.jar.
Extracted downloaded minecraft.jar into THIS folder, not just into lib.
Now it runs fine!
If you open your lib folder and don't see a file/folder named
minecraft.jar, but instead see a whole bunch of files from the download,
then the above will fix the problem. I hope this helps you all.
So all my problems (which had the same error messages as most others) were fixed by altering the java path and making that folder. I'm not even sure the java path did anything useful, but I won't mess with it again... Just try the folder first.

i have the same thing as you how can we fix it
