'Getting 'java.lang.UnsatisfiedLinkError': no lwjgl in java.library.path

Note this is different from this question because it does not deal with linking because it's not asking how to link it via the CLI, but the GUI in Eclipse.

I have been trying to write a simple program using LWJGL. When I add the library to Eclipse (Kepler 4.3.1 on Windows 7 64bit) and write a program, it does not show red squigglies under the the things which use LWJGL. However, trying to run it gives me the following stacktrace:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
    at java.lang.ClassLoader.loadLibrary(Unknown Source)
    at java.lang.Runtime.loadLibrary0(Unknown Source)
    at java.lang.System.loadLibrary(Unknown Source)
    at org.lwjgl.Sys$1.run(Sys.java:73)
    at java.security.AccessController.doPrivileged(Native Method)

    at org.lwjgl.Sys.loadLibrary(Sys.java:95)
    at org.lwjgl.Sys.<clinit>(Sys.java:112)
    at org.lwjgl.opengl.Display.<clinit>(Display.java:135)
    at DisplayExample.start(DisplayExample.java:8)
    at DisplayExample.main(DisplayExample.java:23)

(Yes, that is the example they give first, but I wanted to run it to make sure everything was installled properly)

My question is, how do I fix this error? Note that, even when running in Eclipse, it still fails. If I run something else which does not use LWJGL it works, too. I just downloaded it from the internet - it only had one version, so I assume it was the correct one. From what I can see, none of the other question askers have the same error as me - but if you could point me to informative questions that would be helpful too.

I was following the tutorial here, and it looks like I didn't do the Adding the natives step, or I did it incorrectly.

Follow the instructions in that link and the problem should be resolved:

This is done by clicking the little arrow next to the lwjgl.jar file to show the drop down list. Double click 'Native library location' and select the folder that contains the native files for your operating system and clicking OK. These are located in the natives folder include in the LWJGL download bundle (e.g. On Windows you'd point to the natives\windows folder which contains the *.dll files, On Mac you'd point to the natives/macosx folder and on Linux you'd point to the natives/linux folder).

If you try tu run this code:

public static void main(String... args){
    System.out.println(System.getProperty("java.library.path"));
}

you should get output like this: /Users/yourName/.sdkman/candidates/java/8.0.252.j9-adpt/jre/lib/compressedrefs:/Users/yourName/.sdkman/candidates/java/8.0.252.j9-adpt/jre/lib:/usr/lib

So, you just need to download LWJGL libraries and copy files located at "...native/yourOSname" to one of this folders

That works to me fine!

I solved the issue by adding the lwjgl.64.dll file to the jdk-14.0.1 bin folder
