Troubles running default config

[yghern]

1. Clone repository: git clone https://github.com/everwatchsolutions/json-data-generator.git (1.4.1)
2. Compile using mvn clean package from command line (success), maven 3.3.9, Oracle Java 1.8.0_152, Linux Mint 18.2
3. Copy bin.tar and .jar files to separate directory
4. Modify classes/defaultSimConfig.json by removing nats producer section (only default logger is left)
5. Copy classes/defaultSimConfig.json and classes/normalUser1Workflow.json to above directory
6. Enter above directory and start program using command java -jar json-data-generator-1.4.1-SNAPSHOT.jar defaultSimConfig.json

Expected:
Demo project is run

Actual:
achamier@deathstar ~/git/json-data-generator/run $ java -jar json-data-generator-1.4.1-SNAPSHOT.jar defaultSimConfig.json

When generator is run from target directory it runs without an issue.
I googled some solution, there are several threads which ends in "oh it looks like you forgot about dependencies" but withour real solution, and as far as I can see mqttv3 is declared both in pom.xml and json-data-generator.iml. Any help?
