Unable to install minecraft forge

[gaga654]

When I run the install.cmd file, I get a message about "scala" missing from the path, and then I get 64 decompiler errors (not sure if these two things are related or not). Then in the end none of the source files that should be created actually are created. Any suggestions/help? (What other information do you need?)

Yes, install scala.

Ok, I am no longer getting the message about "scalac" missing from the path, but the second issue still exists - I am getting many "cannot find symbol" errors, all of which are occurring in the AccessTransformer class.

Also, when trying to compile AccessTransformer, it is giving several "package does not exist" errors, missing packages com.google.common and cpw.mods.fml, as well as possibly others.

 

Also, in the readme it says there is a bug which could cause compile errors in jdk 1.6_21 or earlier, and I found that my jdk was in fact only 1.6_17, but after updating it to the current one it still does not work.
