Using documentation on the Apache James website (https://james.apache.org/server/quick-start-cassandra.html), the docker container will not run. The docker-compose file from the instructions is downloaded. Docker-compose up is run as root. Immediately the following error occurs:
james | Error: Unable to access jarfile james-server.jar
james exited with code 1
In addition, the "dockerfile" folder is missing or moved from GitHub, so I am still trying to track down what commands are being run and where the issue could be.
