Failed to remap class.

Hey guys!

I made a market plugin which worked just fine in 1.4.7 and now that I updated it to 1.5.1 it just stopped working. Eclipse is not showing any errors what so ever but when I start my server using the plugin it prints out this error message:

Click the spoiler for the error code.

I would be really greatful if anyone could help me to resolve this issue!

Thanks in advance!

 

Try reconfiguring your plugin.yml, or any other access files you associated with to your plugin.

 

Set the latest craftbukkit.jar as the dependency, that should work.

 

Well, since I am not using any craftbukkit code, then that would be unneccesary, but I believe that you are reffering to the latest bukkit.jar as my dependency?

I tried to do that, but I get the same error as before Hellsing

It turned out to be that I was using libigot, and something was wrong there!

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

i've just hit the same error on libigot. Can you explain what you did to fix it?

I assume because I built it against craftbukkit and am running libigot?

but then why do all of the other plugins work?

 

qwiso

I don't really know, I didn't resolve the error I just made the plugin work by building against bukkit and run craftbukkit. But since we run our server with libigot(because of heroes) my plugin is pretty useless since it only works on craftbukkit...
I am building against libkit and won't recieve any compiler errors and I really can't see why it isn't working!

 

Maybe try updating the java version or so,...I had an error like this once and I fixed by updating my java version..

 

Yes, I solved it last night because I was building on 1.7 and the server plugin was running on 1.6. I was using libigot but am no longer using Heroes in favor of exactly the plugin I'm making to replace it (QCharSheet- will be making the project/repo in the next week or two).
