NullPointerException when executing a runnable jar of the project

[Kuritzu]

Hello, I am using a runnable jar file in order to trigger the recording of the sensor. Until now, i had no problem but recently i got the following error

Tobii: Copying /lib/tobii/x64/tobii_stream_engine.dll into C:\Users\Kurit\AppData\Local/.tobiiStreamEngineForJava
java.lang.NullPointerException
at java.base/java.util.Objects.requireNonNull(Objects.java:208)
at java.base/java.nio.file.Files.copy(Files.java:3112)
at tobii.Tobii.copyResourceIntoDir(Tobii.java:112)

at tobii.Tobii.loadIfNotLoaded(Tobii.java:33)
at tobii.Tobii.gazePosition(Tobii.java:19)
at tobii.TobiiDemo.main(TobiiDemo.java:38)

I understand that when running the runnable, the code is somehow not detecting the connected eye-tracker, I am not sure what I did to trigger this, but the device only seems to work when i start the java code from Eclipse, while the execution of the Jar file won't trigger the eye-tracker to start recording.

Thank you in advance for your help and time.
