Today is a big day.
I have rewritten the entire plugin, now using Gradle, and compatible with 1.17. (New Blocks are supported as well)

Also, the plugin is now open-source!
You can find it on my github, the link is on the main page.

This update is just a snapshot, and not everything is fully tested.
If you encounter any issues, please post them under issues on the github page.

Currently, no new features have been added, this is just a 1.17 compatibility release, but new features will come!

Furthermore, if you want to contribute, feel free to open a PR in the github repo!
