The time for Scheduler Tasks are measured in Ticks. Under normal conditions, there are 20 ticks per second. Tasks scheduled with .scheduleSyncRepeatingTask will be run on the Main Thread Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() { @Override public void run(...

This basic example shows how an application can instantiate a classloader and use it to dynamically load a class. URL[] urls = new URL[] {new URL("file:/home/me/extras.jar")}; Classloader loader = new URLClassLoader(urls); Class<?> myObjectClass = loader.findClass("com.exampl...
