How to correctly setup latest LWJGL libraries to Eclipse?

You can create gradle or maven project and add dependencies which you can generate on lwjgl download page.

Another way - you can download jar

Create simple Java project in eclipse, create folder in project called for example lib and put all jars from archive to this folder

After that go to Project -> Properties -> Java Build Path -> Libraries -> Add JARs... and select all jars from this folder.

Create class HelloWorld from Get started guide and run it. Done.

I've had to do this multiple times as of recent: here's my method.

First, head over to the LWJGL homepage, and click on the DOWNLOAD tab up at the top.

After that, click "Customize LWJGL 3"

From there, select "Release", and click on the modules, modes, natives and presets you want. I usually get the ZIP Bundle with Windows natives and everything included, along with JOML. Hit "DOWNLOAD ZIP" at the bottom, and extract it to anywhere you please.

Now, open up your project in Eclipse, and create a new folder called "lib" or "library". From there, get your extracted JARs from your extracted ZIP file, and put 'em in.

From there, click on your project and hit Alt+Enter to bring up the properties menu. Inside there, click on Java Build Path, then "Add JARs..."

Click on your lib or library file, and select the ones you need, then hit OK.

Congratulations! You've now set up LWJGL 3 in Eclipse! Now it's time to create your src directory and start coding.

As for the natives that used to be .dll files back in LWJGL 2, they've changed them all to .jar files (yeah, it threw me off, too when I made the switch).

(If I didn't explain it well enough, here's the tutorial I used)
