Bukkit

When the server starts, the console shows the plugin starting. Next line it says, "Disabling plugin; Dependencies not met during plugin load". What dependencies are required to run this plugin? Nowhere on the Bukkit page did it say anything about required something.

When I installed it, Sleep folder is created, but no config file in it, just the PlayerActivity.jar. I am using version 7.3.2.

You shouldn't need anything else. The Sleep plugin supplies anything you need itself.

There should be additional information in your server log file as to what you need to do. It might be as simple as restarting your server once more.

Can you see if there is any further information in your server log file?

There is probably a message like: "[Sleep] Unable to add PlayerActivity utility jar to class loader; Restart server to enable plugin"

What version of CraftBukkit are you using?

Had the same issue with 7.4.0. I didn't realize I'd need two server restarts to get it working. The first restart created the Sleep folder containing PlayerActivity.jar, but the plugin still didn't load. Second restart did it.

I have this issue too
