Getting a non-existing library when attempting maven build. Build returns the following:

Your machine has issues resolving SSL certificates. Could be a proxy issue, or an issue with your Java installation (google for "from/to central ([https://repo.maven.apache.org/maven2](https://repo.maven.apache.org/maven2)): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"). Nothing ES related though.
