This is a modpack.
The files are divided up into the following directories,
src/
contains the scripts and tools I use to maintain the manifest file, and build the modmodpack/
contains the configuration of the modpack itself, including configs generated by running the game and zenscript scripts for craft-tweaker
Clone this repo, then create a folder called static/
at the root. Download the latest forge installer (which you can find here). Run the installer from anywhere in your file system, selecting the server option from the available options. Install the server in the static/
directory.
Later, when you run the build script, the files in static will be copied into the build directory.
