Fix can't make eclipse project files(many files)

OS: OS X 10.10 iMac (27-inch, Mid 2011)

I tried to make eclipse project files, but I can't make eclipse project
files.

command:

$ cd ProjectE-master
$ gradle setupDecompWorkspace; gradle eclipse

so eclipse project files are not generated.

I tried this idea:

* build.gradle
assetDir = "eclipse/assets" -> runDir = "eclipse"

make "src", "eclipse" folder
move "main" folder to "src"

$ gradle setupDecompWorkspace; gradle eclipse

files are not generated.
Now, I use this idea.

download minecraftforge source(version 1.7.10-10.13.1.1219
move ProjectE/main to minecraftForgeSrc/src

This idea is good.
Run programs well.

If you unlike this idea, please don't merge this.
