How do i prevent animals from naturally spawning?

The question says it all, ive tried several methods and read and watched everything there was to watch on this subject, yet my server STILL continues to spawn animals. The key word here is naturally, i want to be able to spawn animals via spawn eggs, i just dont want them to be is herds scattered all over the world.

 

It needs to function on a 1.8.8 server and that plugin appears to only work with 1.6.4.

Even without regard for the supported version the config generates no text, i dont want all natural spawns to be blocked just animal spawns. To be more specific i want animals generated by chunks being rendered for the first time to be removed, i managed to stop animals from spawning over time but chunk generated animals are still everywhere.

The link to the plugin on curse. http://www.curse.com/bukkit-plugins/minecraft/nonaturalspawns

The "supports:" line says 1.6.4.

 

/gamerule doMobSpawning false

 

1. Plugins could still work even though they were made with an earlier version. I still make my plugins for 1.7 and I know they will work for 1.8
2. You can't say it doesn't work until you actually proven that it doesn't work. eg: try it out on your server

Also you may not need a plugin for this anyway. In the bukkit.yml, you can adjust the max spawn count for certain mobs.

 

What value? In the config file there's only "worlds: {}". I put true in between the brackets. Replace the brackets with true, and simply replaced the entire text with true. Nothing changed.

 

Alright i went into config and set false to the "NATURAL" and "CHUNK_GEN" settings for sheep, pigs, cows, and chickens. However this led to no results, when i enter new chunks those animals continue to spawn.

 

I installed the plugin, started the server, shut it down, changed the settings, then booted the server up again.

 

Yea i dont know what to tell ya. It's simply not working.
