I'm @tanmibts co-worker and confirm these same steps work on my machine but not theirs.

I'm running MacOS Mojave 10.13.6. Maven was installed via Macport. Maven and Java versions:

$ mvn --version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T12:39:06-07:00)

I found the same issue, here.
The difference is in maven version.
Version 3.6.0 it's OK.
Version 3.6.3 it's NOK.
I believe it is related with #MNG-6713

A simple pom.xml can be used to reproduce the error, like this:
