    I've been working on a plugin for my server. It is supposed to find my radio station's stream info, which it does correctly. I want it to broadcast the info every 10 minutes. I've had no luck so far.

    Out of all the things I've tried, my outcome is always "Plugin attempted to register task while disabled."

    I mean everywhere it says to put the scheduler method is in the onEnable, and I get the above message every time.

    Code without the scheduler (and yes, only one file):
    Code:java

    92.         }//If this has happened the function will return true.
    93.             // If this hasn't happened the a value of false will be returned.
    94.         return false;
    95.     }
    96.  
    97. }
    98.  


    Where should I put the scheduler, because I want to execute it every 10 minutes after the plugin starts. What do?

    First off, get rid of static.

    As for the task, try registering it to run after 1 server tick (rather than instantly).

    Don't use the static plugin field, that is unnecessary. You are doing it wrong anyways. Use "this" in the place of plugin.

    Oh wow, simply changing plugin to this got it working. Huh...
