How do i compile the multiverseinventorys invsee++ files?

[pxlarified]

Im not really familiar with how it works and after following the "guide" nothing really happend, so i think i did something wrong. I have JDK, Java and Maven installed.

Run mvn clean package in the root directory of the repository, as described in the README.md

I managed to compile the invsee++ multiverse file, but paper is failing to load it.

That maven module does not have a bukkit plugin. Instead, its files are included in the main bukkit plugin.
Please be aware that multiverseinventory compability was never completed, the issue for it is still open: #32

Mhm interesting. What is the status on it, is it working limited or doesn't it work at all?

[Jannyboy11]

It doesn't work at all.

[pxlarified]

Mhm ok... Are there alternatives for it?

[Jannyboy11]

There is PerWorldInventory still, but it hasn't been maintained in a while.
