sun.security.validator.ValidatorException in Maven dependency download

During maven setup, i got the following error:
Error transferring file: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Luckily there was solution for this problem available at this post.
