Compatibility issue with WorldGuard in Tekkit 2.1.1 server

The topic really states the problem. According to my server, I am running a Minecraft 1.1 verson of CraftBukkit, which is included in Tekkit 2.1.1. Code is here:

Code:

19:55:02 [INFO] Starting minecraft server version 1.1
19:55:02 [INFO] This server is running CraftBukkit version git-Bukkit-1.1-R4-b1938jnks (MC: 1.1) (Implementing API version 1.1-R4)

So, I then go to the WorldGuard plugin and insert the correct version (Worldguard 5.5.1) for API 1.1-R4 into my plugin file. Unfortunately, i get this error that it won't work for some reason.

Code:

20:15:23 [INFO] [WorldGuard] Loading WorldGuard v5.5.1.
20:15:23 [SEVERE] Error occurred while enabling WorldGuard v5.5.1 (Is it up to date?): com.sk89q.minecraft.util.commands.SimpleInjector.<init>([Ljava/lang/Object;)V

at net.minecraft.server.ThreadServerApplication.run(SourceFile:465)

So, does anyone have an idea as to what i need to do? All of my other plugins are working and i have worldedit.jar in my plugins. I've also used version 5.5 of World guard to no avail as well!

Code:

20:35:50 [INFO] [WorldGuard] Loading WorldGuard v5.5.

Thanks for the help!

 

I've been having this exact same problem with every build of Worldguard I try to run on my Tekkit server. I've tried every build of WG for minecraft 1.1+ with still no success. It's a shame, I was actually hoping this thread would have some helpful replies already.

 

You're better off posting this on the Technic forums.

Someone posted a version of WorldGuard that supposedly works with 2.1.1, FWIW.

 

Duder, I actually found that .jar file of world guard that works on the technic forum minutes after posting this topic. Also, You'll have to edit your server .jar file in order to fix the bug that allows people to place blocks on protected areas. It's not as hard as it might seem. I'd upload the jar file here if i could. If you recommend credible website to host it on, i'll shoot it up there and link it for ya.
