Clicking the button or link 'Follow the Project' is giving an error

When I login to my organization’s circleci website, I could not see the “create a project” button for the repo for which I am one of the admin, but the button “Follow the project”, against the name of the repo, which I clicked. I got this message “Something went wrong when trying to follow your project”.
Upon verifying, I found the following message trace…


#!/bin/bash -eo pipefail
mvn clean test

/bin/bash: mvn: command not found

Exited with code exit status 127

CircleCI received exit code 127

I don’t understand why Circleci is not able to find the maven build tool. Should we include any steps in the config.yml file for that ?
This is my first config.yml writing for me.

To give you the config.yml I am using, it is here…
