JAR can only be executing from the project folder

When I tried to run the JAR as java -jar owl2bench/OWL2Bench.jar 10 EL 20, I got an exception:

This makes the JAR runnable only if the files are at the same level where the JAR was invoked. A possible improvement would be to allow adding a path to the folder where the input files live

Thank you for your suggestion. I will update it.
