How to run WhiteboxGis under linux system only with command lines or terminals?

I have to run the Whitebox on Linux system, but I am new to use Linux. Therefore, I do not know how to run the whitebox software on Linux. The followings are what I tried to run the software:

~/Desktop/rhessys/Whitebox_3_2_1$ java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
~/Desktop/rhessys/Whitebox_3_2_1$ ls
lib  logs  README.TXT  ReleaseNotes.txt  resources  WhiteboxGIS.jar
~/Desktop/rhessys/Whitebox_3_2_1$ java -jar  WhiteboxGIS.jar
~/Desktop/rhessys/Whitebox_3_2_1$ 

After typing "java -jar WhiteboxGIS.jar", the software was no response. Or it was running? If it is running how can put data into the whitebox to calculate?
