Sorry for the delay, I was on vacation.

So, your problem is because you are using bukkit or spigot 1.8 which don't include gson. To solve your problem, download gson, then open it as a zip and copy all the content of gson-2.8.1.jar into you spigot.jar or into AddLight-4.2.0.jar.

Once gson will be in your classpath, your problem will be solved
