Currently omero-build is the primary repository for checking the build status of downstream PRs, leading it to have a more complicated travis script, see https://github.com/ome/omero-build/blob/master/travis.sh
Adding in Bio-Formats to that script would further complicate matters. Perhaps this repository is a more natural location for that. However, to do so, it will be necessary to either spin up a devspace and check its status with a single script or run parts of this repository with less overhead.
