Hi over the last week i have been trying to get minecraft forge 1.6.4 to run through eclipse so i can work on my mod. When i searched through the folders in windows explorer(file viewer) i managed to find the file that it is having trouble finding.

Also i decided to make the basic file of a forge mod, but i get lots of errors with the imports of cpw.mods.fml.common etc. I think my problem is that it cant find these files because of a placement error in the folders but i cant be sure.

the exact error shown in eclipse is:

java.lang.ClassNotFoundException: cpw.mods.fml.common.launcher.FMLTweaker
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)

please help,

First it was small and friendly and wanted to play games and not sit still and now its big and complicated and has extra parts and doesn't make sense and doesn't know what it wants to be and struggles to make ends meet, while still maintaining reminiscences of her childhood memories.
