Trouble compiling fork due to seemingly broken dependencies (I think).

[Nano-Blue]

Hi, I am aware that this is probably entirely down to me being new to programming in java but I hope you'll bear with me nonetheless, I am currently trying to make a plugin that can regenerate broken and placed blocks, This plugin for I think clear reasons seems ideal for what I need to do, as far as I can tell it should be a matter of linking into block place and break events and saving their data in the same way as the explosions already implemented, I feel fairly comfortable with that however I am struggling to get the plugin to compile having downloaded the source code, these are the errors I'm getting:

I have already dealt with some dependency errors and the ones that remain all seem to reside inside 'NMSWrapper_v1_16_R3'. Honestly after looking through all the classes that's also the one I'm having the hardest time understanding.

I just don't know where to find or how to properly install the packages however hopefully after getting this sorted i'll have a better grasp of the issue.

I'm going to attach a bit of the code however if you want access to more just ask and I'll upload it - I haven't changed anything about the file itself that I'm aware of except for changing the first line to package 'me.blocks119.aurauriaregenerator.nms;' along with similar simple path changes in other files.

Many thanks in advance.
