Launching

This tutorial assumes you are using Eclipse. If you aren't, you will have to figure out how to add the files on your own.

Delete the "Server" project. You won't need to compile it.

Then, remove all unresolved libraries, and then add ALL libraries that are in jars/libraries.

Add the natives folder to the "Native Libraries" section of 1.XX.jar. For example:

The folder name should be 1.XX-natives.

You should be ready to go. If you get a glitched icon, head over to jars\assets\indexes and make sure 1.13.json is there. For some reason, I had 1.13.1.json there, which I renamed to 1.13.json to fix the issue.
