Solved Plugin already initialized strange error

Currently, I'm trying to fix an issue with the Beta build of Craftbukkit and my plugin.

The stack trace says the plugin has already been initialized here:

Code:

Now, at line 24, it's the same line I've used for a few years:

Code:java

public class Main extends JavaPlugin implements CommandExecutor, Listener

The first stack trace said like 6, 46, 289 which is this:

6:

Code:

public class Configuration{

46:

Code:

    public void onServerReload(ServerCommandEvent event) {
        Scheduler Scheduler = new Scheduler();
        Configuration Configuration = new Configuration();
        if (event.getCommand().equalsIgnoreCase("reload")) {
            if (Configuration.getReloadSafetyTeleport()){
            Scheduler.onServerReload();
            }
        }
    }

289:

Code:

 @EventHandler(priority = EventPriority.HIGHEST)
    public void serverReloadEvent(ServerCommandEvent event) {
        EventHandlers EventHandlers = new EventHandlers();
        EventHandlers.onServerReload(event);
 
    }

Thanks for the help!

 

Why don't you show us the entire class? Even though the stack trace points out lines of the most relevant code. More code may be needed to solve the problem, which is true in this case.

 

Colby l You don't need to implement CommandExecutor in the same class that you instead JavaPlugin. JavaPlugin inherits the CommandExecutor interface.

 

That seemed to do the trick, thanks!
