Check if task is running

Hello guys! I have a fairly simple part of code here with a command and an scheduler. So whenever I type the command the task counts down from X to 0 and then does something. My problem is that if I type the command twice there are two tasks running. So I want to send the player a message and cancel starting a new task when there is already one running. Here is my code:

Code:

    int cd; //Is defined where it belongs to 

Code:

if(args[0].equalsIgnoreCase("start")){
             
             
             
             
             
                p.sendMessage("Started");
             
             
             
                cd = Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {
                 
                 
                 
                 
                    Integer amount = Integer.valueOf(15);

                    @Override
                    public void run() {

                        if(amount != 0){
                            Bukkit.broadcastMessage(amount + " seconds left!");
                            amount --;
                         
                        }else if(amount == 0){
                 
                           p.sendMessage("Finished");
                          Bukkit.getScheduler().cancelTask(cd);
                        }
                     
                     
                    }
                }, 20, 20);

            }

So everything works fine, the only thing that I want to add is a check if the task is already running.

How can I do that?

Thank you so much and have a nice day!

Check if both are false before continuing to create a new task.

 

Is it just me, or this is decompiled code?
I don't see any reason why you use the object Integer rather than the primitive int.
