Working with Cucumber Runner for BDD in Katalon studio 5.7

This is a companion discussion topic for the original entry at

How can we run multiple feature files in specific sequence with CucumberRunner class ?
e.g:- if I have 3 feature files (File1.feature, File2.feature, File3.feature)
Then how I can run these files in a following sequence ?
File 1 then File 3 then File 2

Using the latest version of Katalon 6.2 but getting error when running BDD tests from this video github example. how can I fix that so it runs and I can add my own tests.
