Caused by: java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path

[Zombiedevice]

I know what this exception is, but why does it only do this when I export the project as a jar and run it? The native libraries are set, it runs perfectly fine in Eclipse so why does this exception occur when I run it as a jar?


Here is the full exception:

When running from the command line you'll need to add -Djava.library.path

e.g. java -jar Launch.jar -Djava.library.path=.

Or something close to that

is there no option to include the natives into the jar so that i have one jar which runs under win/linux/mac and the user has not to set any paths?

no, java provides no such option.

you can however manually extract the natives somewhere and point to them to get it to work.

Considering natives are usually somewhere relative to the .jar, you could do something like this:
