Frequent build failures on Travis

    Details

      Description

      Lately our Travis-CI builds are failing very frequently, and interestingly during the installation of dependencies phase. The failure is strange, namely that a Docker container cannot be started because one is already running:

      First of all, we shouldn't be starting Docker containers during this step. Secondly, there are no existing containers: the .travis.yml file already is running docker ps -a several times prior to this and there are no containers running. Therefore, it's likely something to do with the recently-upgraded Docker Maven Plugin.
