Are there any detailed instructions for how to use css-validator.jar?

Question

I am trying to use the local version of css-validator, but can't seem to get it to work. I think everything is set up correctly, but whenever I run it with the command given as an example by w3c, it gives errors. Some people say I am missing something in my path or something like that, but I am not sure which path they are talking about (build path or environmental variables), and I don't know what exactly needs to be put into this path either.

I have looked for detailed instructions, but the most detailed instruction I found was that it needed to be in lib (which lib, I see hundreds of them). For reference, here is the documentation of css-validator.jar that I have found so far (which is not much, consisting of nothing but a command to run in cmd prompt): http://jigsaw.w3.org/css-validator/DOWNLOAD.html

This is the part most relevant from there: Note : the css-validator.jar file must be located at the exact same level as the lib/ folder to work properly.

Also, I tried using the jcabi.w3c wrapper(which I thought it said it only needed one dependency, but another website said it needed more, including glassfish jersey-core), but it talks about all these dependencies that I don't know where to put them (its xml, but it doesn't seem to match an Ivy document) and many I don't even have or know how to set up.

The w3c wrapper simply says "No main in selection" when I try to run it (which is a message I have never even seen before in cmd). So how do I get this thing working? Where is the documentation (more than 3 lines that W3C provides please,)?

Also, the error I am getting when trying to use css-validator.jar:
