Can't run tigase server

[mgben16]

Describe the bug
Hello, I'm trying to setup tigase server for a school project. I'm using Ubuntu 20.04.3 LTS. After cloning the repository (git clone https://github.com/tigase/tigase-server.git), compiling using maven (mvn package test) and setting JAVA_HOME in etc/tigase.conf file, I get the following error when trying to run the server (in tigase-console.log file):

==========

How could I solve this problem?

(This is my very first service administration project, so I apologize for any errors or missing information)

I would suggest taking a look at Quick Start guide and using pre-build packages available in release section (especially if this is "administration project").

Otherwise, you would have to include all require dependencies (xmltools, utils and jdbc drivers for the selected database at the very least).
