I need to add an external library named ControlFX in my project. Here is the official link to download it: https://github.com/controlsfx/controlsfx
The issue is that this file is .zip type. So, I'm really confused about how can I add it as a library to my project (it doesn't include.jar files inside).
Any idea, please?
Check out How to add external library properly in Eclipse? if you want to add it manually, but it's very much not advised if you don't know what you're doing.
If you want to learn the proper way to use external resources look into how to use Maven or Gradle to incorporate libraries into your projects.
