Bukkit

In reply to darklandmc:

 Sounds like you haven't granted them the permission to edit opened inventories. Your best bet is to use a system such as LuckPerm's verbose mode that tells you real-time what permissions are being checked for whom and how they evaluate. That will help you to track down any errors in your system's configuration.

 Doable but would need some fiddling to preserve existing behavior. Please open an issue so I don't forget.

 1.17.1 should not require any changes on OI's end from 1.17, so I guess the answer is yes, 1.17.1 support has been out for over a month.

In reply to OfficialOffTopicGaming:

 If you poke around at all there or glance at releases here on Bukkit you'll see why that's the case. Unfortunately, I can't edit the old release location message.

In reply to bandithello1:

See lishid#173. Update your server, downgrade Java, or fork OpenInv yourself (or pay someone to do it for you) and backport the changes to support Java 9+ to the 1.12 module.

You can read my thoughts on 1.12 and other outdated versions at lishid#185.

I would love if this plugin could be backwards compatible with all versions instead of one build being for one or two versions

 Any time you want to maintain the same code in 20+ places to support for outdated versions that a tiny fraction of people use running, feel free to step up to the plate. Backporting changes is a tremendous amount of boring, thankless work - more complex fixes can take hours of copying, pasting, and slightly adapting code. Sometimes the area's completely different and requires a deep dive into NMS to figure out what changed. Support for Java 9+ is a particularly complex beast because it involves overwriting pretty much every method to direct to new variables. You can't just hope inventory logic didn't change between versions, you have to do a comparison.

 A build for 1.17 was uploaded 2 days ago and has just been approved. If you're wondering about updates, check GitHub.

In reply to lovelessduck48:

 Update your server. I think I need to add a giant red statement about that, because you're the 3rd person to get in touch about a Spigot bug that was fixed half a day before the release of OI on GitHub, let alone 2 days later when Bukkit's approval process finished.

Please, please, when you are using a fresh MC update, ensure that you are actually running the latest server version before trying to contact individual plugin devs. It wastes a lot of both of our time. I have to check that the issue is that you haven't updated, and in the communication time between your server isn't running the way you want it to.

 Make sure you're turning off silent/any container when using a vanish plugin - many of them are incompatible because they implement their own technique for handling containers, which will lead to clientside desync. You can do this by creating aliases using Bukkit's commands.yml, i.e. /vanish -> /openinv:sc off, /openinv:ac off, /yourvanishplugin:vanish. Alternately, your vanish plugin may have a compatibility mode in its configuration.

There is no DropBox link on any sites I maintain OpenInv on. One assumes you tried to download it off the ancient Bukkit forums thread for some reason, which is purely there for historical purposes.
