I've tried every option explained step by step here and here: and here
And I can't get it to work.
What I want to do is pick this project: , however it may be done (I've tried both through maven and git), and use its code in eclipse. And what I mean by that, is that I get to the point of seeing the folders in eclipse, but I can't create packages since it's not a java project, and if I mess up the code on the files that appear, it doesn't give me a warning nor in general interacts with said code.
So I guess I'm missing some piece of knowledge and I don't know where else to look for it. What should I do to use that project in my eclipse, and create my own code that calls and uses the classes and methods from said project?
Thank you in advance.
