@CroseBoy_99
What line is 72 ?

 

Code:

        FactionsPlugin.getInstance().getLogManager().formatMessage("Death-banned", deathBan.getPlayer().getName() + " - " + deathBan.getKiller().getName());

 

One of those methods returned null.

 

Try debugging by printing the Objects returned by the methods. i.e

Code:

FractionsPlugin.getInstance()

or

Code:

deathBan.getPlayer()

and see if any return null.

 

@ChipDev By the way, do you know how to find the CraftBukkit v1_7_R3 version? (I need it now and I can not find it.)

 

@CroseBoy_99
I don't think so; Buildtools may not have that specific version and you should not trust anyone else to give it to you.

Why do you need that version? Unless you need it to be on 1.7 (in which case, you already have a 1.7 jar), there should be no real difference between R3 and R4 (unless you are working with NMS, and even then reflection Utils will help with this.)

 

import org.bukkit.craftbukkit.v1_7_R3.*;
import org.bukkit.craftbukkit.v1_7_R3.entity.*;
import net.minecraft.server.v1_7_R3.*;

Is it clear enough? If not it is necessary for a plugin.

 

@CroseBoy_99
Just change the 3 to a 4. The only thing that changed between those updates is the path.
