How to execute?

[the-REAL-beautysleep]

Downloaded this from http://www.graphwar.com/ as the .jar file http://www.graphwar.com/graphwar.jar:
When I open it, it just opens as a folder to be extracted

Screencast.2022-02-23.14.43.48.mp4

system: ubuntu 20.04

I also tried

`$ cd Downloads

$ java -jar ./graphwar.jar XXX.XXX.XXX.XXX

Do you have /usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so?

I didn't at the time, just installed it there.
sudo apt install openjdk-11-jdk

now I get
"Downloads/graphwar.jar' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit."

so I did the following, with success

on terminal

git clone git@github.com:catabriga/graphwar.git

cd graphwar

make

java -jar graphwar.jar

all works perfectly so far, thank you !
