[1.12.2] "no lwjgl64 in java.library.path" Crash


Recommended Posts



I've recently been working on my mod for Minecraft, I was able to run the Client on Eclipse up until recently when I keep getting this crash:

xception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl64 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 net.minecraft.client.main.Main.main(Main.java:42)
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release


I've tried to designate the native build location to my lwjgl-2.9.4-nightly.jar and similar jars for my native library location in the JRE System Library, but no solutions were made. 


Any help is appreciated, thank you!
