But I noticed the coordinate of the artefacts may have changed after version 9 (group:`org.eclipse.jetty.websocket`, artefact: `wesocket-server` -> `websocket-jetty-server`).

�� ��  I've just tried using 10.0.5 and I get this error:

It seems this needs [SPI Fly](https://aries.apache.org/documentation/modules/spi-fly.html) now...
