The plugin under buildtest.sh will provide the plugin to run the base build.sh test which will trigger the tests of the main Avro projects, and the sections below lang/*/build.sh. To run this, use:
test-patch --plugins=buildtest --user-plugins=share/precommit/ --run-tests --empty-patch --docker --dockerfile=share/docker/Dockerfile --dirty-workspace --verbose=true
Note, that this is still a very crude implementation of Apache Yetus, and in the future we would like to refine this to provide plugins for the different languages.
