I have been trying desperately to find a way to delete or replace plugin files on a CraftBukkit server without shutting down a server and interfering with everyone's actions on the server. Can anyone tell me how I might be able to achieve this? I have tried using PlugMan and PluginManager plugins to try and unload the plugins, but this still does not allow me to delete the plugin .jars without stopping the server. Just disabling the plugin will not work, so the Essentials command for disabling plugins or any other plugin disabling commands are useless. If anyone can help me with this problem, I would be very grateful. I would use this information to add a new auto-updater that would automatically download new versions of the plugin, add the new version to the server, and delete the old version. If that happens, I will formally thank you for your help in developing this advanced auto-updater both on the page for each plugin and in the changelog for each plugin that has the updater. Thank you in advance for your help. Note: If your comment is just going to say that it's impossible, please explain why. If your comment says something like "you can't" and that's all, I will be angry with you.
