This means your build process does not have the certificates required to access that repository.

You may need to install them manually.  If the machine doing the build connects to https://packages.atlassian.com/maven-external/ does it get the same error?

I tried accessing link https://packages.atlassian.com/maven-external/ using internet browser, I can access it without any error, on the machine doing build process. 

[Nic Brough -Adaptavist-]

Yes, your browser is capable of negotiating a secured link with https sites.  Your build process does not.

The most simple thing to do is look in the browser, and grab the certificate it got from the site to encrypt the connection.  Most have a padlock sign next to the url bar which has an option to view the certificate with a save-as or copy function.  Use that to get the certificate and install that in your build.  (For a maven build, this can be installing it in the Java key store, but that might not be the "right" way to do it for you)
