Define somewhere in your secrets:
  export JENKINS_SERVER=''
  export JENKINS_USERNAME=''
  export JENKINS_PASSWORD='' -- token located under your users settings

Usage:
  jenkinslog [--gff|--stat] <jobname> <buildid>

Example:
  jenkinslog build-name 900 -> get logs for build-name/900 Jenkins build
  jenkinslog --stat build-name 97      -> display time stats and errors only
                                           for build-name/97 Jenkins build
  jenkinslog --gff build-name 97       -> Get test Filter for Failed tests
                                        (FILTER_REGEXP value)
