Thanks for the report @e-lo!

From a quick look it looks like this is because the maven repository hosting the Conveyal gtfs-validation-lib is hosted at HTTP and not at the secure HTTPS:
http://build.staging.obanyc.com/archiva/repository/releases/

The equivalent HTTPS link doesn't seem to work:
https://build.staging.obanyc.com/archiva/repository/releases/

I opened a PR here to see if we can get CI to pass with the HTTPS URLs anyway:
#400

If that doesn't work other possibilities are:

1. Configure Maven to allow HTTP for this repo - https://stackoverflow.com/a/67441519/937715
2. Get Conveyal to host the Maven repo at HTTPS
3. Remove dependency on gtfs-validation-lib and replace it with MobilityData gtfs-validator

I just set up a simple GitHub Action to see if changing to HTTPS works in PR #401 (the other PR used Travis which isn't working anymore).

Nope, HTTPS URL doesn't work:

Remove dependency on gtfs-validation-lib and replace it with MobilityData gtfs-validator

Obviously this seems like the end goal solution, but if this is a ways out an interim fix would also be very much appreciated if we can find one that works.

@e-lo This issue should now be fixed in the main branch if you want to give it another try!
