i did everything and my forge hase some scala librarie problem.

You're missing the libraries, if you used the installer they should of been downloaded for you. But you can manually place them by copying the libraries folder from your .minecraft folder into your mcp/jars folder.

I had this issue but was able to fix it.

 

After successfully running the install.cmd pictured here:

 

 

 

and then opened eclipse to find this wonderful mess!

 

 

 

To solve this, I opened up the properties of my project

 

 

 

Navigated to the "Java build path" tab, and the Order and Format tab, and checked all of the boxes you see here.  If you aren't at this point, let me know I can I can get you there.

 

 

 

 

Weird, I'm doing that and I still have the errors.  I even installed a fresh version of Minecraft 1.6.2 and still nothing.

 

Missing these particular files(lzma-0.0.1.jar, launchwrapper-1.3.jar, asm-debug-all-4.1.jar) and even the libraries folder in .minecraft still doesn't have them.  I'll delete the .minecraft folder and rerun the launcher and see if it downloads them for me.

Instlal Forge on the client then run it, it'll download those files, Mojang moved servers, nothing we can do for older versions just use 953+
