Another one of these lovely errors.
I've been wrestling with this for about a day now, and after some thorough forum lurking, googling, and hair pulling, have gotten no closer to solving the issue.
I am trying to setup forge so I can start modding. I've downloaded the latest version, 10.13.1.1217 (and have also tried with several of the earlier versions, with the same result.)
I am running Windows 7 Professional 64bit.
I've got Java 7 and the SDK setup. I had Java 8 installed, but I uninstalled it. The PATH and JAVA_PATH system variables are setup correctly.
I extract the contents of the Forge SRC zip to a new folder. Then I open up the console, and enter
>gredlew.bat setupDecompWorkspace
Then I get this:
(I replaced my user folder name with USERNAME)
When I browse to C:\Users\USERNAME\.gradle\caches\minecraft\, there is no Assets folder inside of it, which I've gathered there is supposed to be. All that is inside it are two folders: "de" and "net".
I have tried running this with --refresh-dependencies as well as setupDevWorkspace and there are no changes.
Please help!
