JSON File troubles

I was browsing the modding git, and it says in there I’d need a package.json and correct me if I’m wrong, you cannot “create” a .json through Eclipse? It’s been quite a long time since I had to last use it so if I am wrong, may I get a pointer in the right direction?

You can just use Notepad or Notepad++. An example package.json is on the modding wiki.

How would I go about adding it to my Java project?
