This helped me out a lot in getting my environment setup. I am still running into some problems with the run configuration though.
I have my run configuration pointed in the working directory to the following location ${workspace_loc:Minecraft/lib}
Which points to my location F:\minecraft modding\mcp\forge\mcp\mcp\jars\libraries. I have also tried several other locations that contain the jars file, as well as the main part of the jars folder.
Would pointing to a system file accomplish the same result for the run configuration?
Below is my runtime error on trying to just run the 1.6.2 environment to make sure that it works beforehand. Which I believe would be fixed with the run configuration pointing to the correct location.
