Plugin Help Essentials Error Not Loading.

Recently thought i would try Essentials but i keep getting an error when it launches.

Code:

02:38:58] [Server thread/ERROR]: Error occurred while enabling Essentials v2.13.1 (Is it up to date?)
java.lang.NoSuchMethodError: com.google.common.cache.CacheBuilder.maximumSize(I)Lcom/google/common/cache/CacheBuilder;

Anyone know what is going on here i'm not super smart with coding and everything i just dont understand if i am doing something wrong im pretty sure i have the most up to date one.

 

When running 1.8, you need to use the modified version of Essentials created by the Spigot folks. Read the instructions for 1.8, it has a link to the Essentials builds you need.
