Cucumber for Appian - Not able to run the sample feature file

Hi,

I have been struggling hard with this error and am not able to advance any further due to this -

Am trying to run the Tempo Navigation Example feature that comes part of the cucumber for appian jar.

I followed all the steps mentioned as per the playbook and also this - https://medium.com/@mlvandijk/getting-started-with-cucumber-in-java-a-10-minute-tutorial-586652d2c82 but still in vain. Am using IntelliJ IDE.

1. Could anyone please help me understand this issue and how to fix this?

2. For navigating to a native URL should I be defining the URL using scenario outline with relevant example? or is there any other way?
