Hi,

 

After I have followed the client install instruction in the wiki I get stuck (program freeze and java exception, see below) at the "Updating Mincraft"/"Done loading" screen.

 

The java exception:

 

java -Xincgc -Xmx2048M net.minecraft.LauncherFrame

Exception in thread "Thread-5" java.lang.NoClassDefFoundError: o

I am using Ubuntu 12.04, Sun java 1.6.0_26, mincraft.jar (downloaded 2012-07-24) and minecraftforge-client-3.3.7.135.zip. Nothing more.

 

After looking through this forum I have tried the following with the same result:

1) Using gnome's achiever adding the files from forge to mincraft.jar.

2) Using Ark (as mentioned in a different thread)

3) Extracting all files (using both of the above archivers) to a directory

4) Running the above "class-packages" directly (pointing to net.mincraft.LauncherFrame) or using the original manifest file in the jar

5) Removing the META-INF directory only makes java not finding the main-method... do not see the point of doing that!?

 

Sorry, but I do not get a ModLoader.txt file!

 

The "o.class" does not exist in neither mincraft.jar nor forge.zip so am I missing some other code?

Thank you for your attention,

...Roger

Deleting META-INF is almost always required for installing mods. Are your archivers merging folders and overwriting files correctly? Anyways, when installing forge tot he client, ALWAYS delete META-INF. Only when installing to a server should you leave it be.

 

I'm sorry if none of that's useful. I know literally nothing about Ubuntu.

For note you should update to java7 if you are using ubuntu 12.04, java6 is no longer supported in it, but that is not your problem.

 

Always be sure (for now) to delete META-INF.

 

And there will always be a stack trace. 

Thank you Zero and OvermindDL1 for your concern. 

 

If I delete the META-INF directory, java will not be able to know which class the main-method is, and thus will refuse to start anything. 

Please tell which class-file I should give as having the main method (I have used LauncherFrame.class which give me the "usual" login).

 

Also (as stated by 3), I have unpacked all files to a directory and started the LauncherFrame directly (in this case, the META-INF directory is ignored by java), but with the same error as originally is reported.

 

Sorry, but I think I am still stuck. 

 

You should not be modding the launcher, you should be modding minecraft.jar that the launcher downloads.

Forge is installed to .minecraft/bin/minecraft.jar and the META-INF is deleted in there too.

 

You should not be modding the launcher, you should be modding minecraft.jar that the launcher downloads.

 

Is that what's going on? I'm confused anymore...

Perhaps follow a youtube video tutorial for modding it?  That should help clarify it well.
