Solved .getScheduler().runTaskTimer - Crash...

Ill post my class here:

Code:

package me.fresser.DarkRp;
public class GeneralGameTicks {
public DarkRp plugin;
 
public GeneralGameTicks(DarkRp plugininstance){
plugin.getServer().getScheduler().runTaskTimer(plugin, new Runnable() {
public void run() {
 
/*for (Player p : Bukkit.getOnlinePlayers()) {
p.setFoodLevel(20);
p.setSprinting(false);
 
Location loc = p.getLocation();
loc.setY(loc.getY() - 2);
/*if(loc.getBlock().getType() == Material.QUARTZ_BLOCK){
if(plugin.blue.contains(p.getName())){
if(p.getHealth() < 20){
p.setHealth(p.getHealth()+1);
}
}
else if(plugin.red.contains(p.getName())){
if(p.getHealth() > 0){
p.setHealth(p.getHealth()-1);
}
}
}
else if(loc.getBlock().getType() == Material.QUARTZ_ORE){
if(plugin.red.contains(p.getName())){
if(p.getHealth() < 20){
p.setHealth(p.getHealth()+1);
}
}
else if(plugin.blue.contains(p.getName())){
if(p.getHealth() > 0){
p.setHealth(p.getHealth()-1);
}
}
}
 
 
}
}, 1L, 2L);
}
}

Even without to code inside "public void run(){" it generates this error:

I cant see the problem, ecilpse cant neither.

plugin.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable()
doesnt work as well.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

plugin is null.

 

Ty lolmewn, nice stat plugin btw, i have used it a lot.
But why is it null, when it isnt null in my other classes with same method?
EDIT:
I have written "public DarkRp plugin;" instead of "final DarkRp plugin;"
EDIT 2:
Also forgot the line: "this.plugin = plugininstance;"

ty a lot!
