This is an enhancement to the docker image, not a issue.
I would like to see an option to change the server type on container creation. What it does is simply check for the jar file, if it exists, it does nothing. If it doesn't exist the container will use the server type you specify on container creation. (ex. vanilla or spigot) this allows you to download the latest vanilla Minecraft jar (to skip spigot.jar build) or build the spigot jar.
