I start my server and when it gets to "[Gringotts] Enabling Gringotts v2.9" it gives me this error:

[20:50:14 ERROR]: Error occurred while enabling Gringotts v2.9 (Is it up to date?)

2.9 is missing ebean server.

But 3.0.0 snapshot (which includes the ebean server again) does not work for me still.

Stops loading with errors:
