Not sure if this has interest, but I got https://jbang.dev working with sponge so you now can do:
curl -sL https://sh.jbang.dev | bash -s -- app setup && jbang [email protected]/jbang-minecraft
or if you have jbang already installed just do:
jbang [email protected]/jbang-minecraft
This will download jbang and java as needed so the setup is greatly reduced.
In addition you can use jbang to develop script like plugins without having to use a full maven setup.
See more at GitHub - jbangdev/jbang-minecraft on how to do that.
