Plugman or some other plugin manager

Hello i’d really love a plugin manager such as plugman so i can reload, enable, disable, and load up plugins without restarting the server. Thank you!

does not exist and most likely never will, here’s a discussion about it in 2014 https://forums.spongepowered.org/t/plugin-reloading-enabling/684

the only thing that will ever be supported is reloading, but it is up to each plugin to implement that, see Event Listeners — Sponge 7.2.0 documentation

Reloading damages servers, Last time i used it, it badely messed up world chunk generating and i had to reset the whole server

again, sponge’s reload does nothing by default
each plugin has to implement it… so if you had issues that was one of your plugins

I can see from the click counter on that link that you never actually opened it. When you run /sponge plugins reload, it just sends an event to all plugins. The plugins can do whatever they want when that event happens, but that’s all it is - an event. Plugins cannot be dynamically unloaded and loaded and reloaded at runtime.
