<!-- The reason for the existence of this file: Some time ago, Travis CI switched to using 'google-maven-central' at
     https://maven-central.storage-download.googleapis.com/repos, which is slow and does not contain recent versions
     that are actually present in Maven Central. Because of this, automated Travis builds fail when the dependabot-preview
     plugin discovers a new version of one of our dependencies. With this file, we add the maven central back.
