I need help with ClassNotFoundException

When I try to load my plugin with craftbukkit, I get the following errors:

Code:

SEVERE: Could not load plugins/LightVote.jar in plugins: null

This is my plugin.yml:

Code:

name: LightVote
main: com.bukkit.XUPWUP.LightVote
version: 1.5

And if I open the jar with an archive manager I get the following file structure:

Code:

META-INF
 - MANIFEST.MF
com
- bukkit
- - XUPWUP
- - - LightVote
- - - - some subclasses
- - - - LightVote.class
plugin.yml

How do I fix this?

 

I also have this problem, I would appreciate an answer

EDIT : http://forums.bukkit.org/threads/pl...all-plugins-need-to-be-updated.530/#post-5553

Would that be it?

 

Not in my case. Also, it is a ClassNotFoundException, so if it would be an invalid class, it would say something else right?

changing plugin.yml to

Code:

name: LightVote
main: com.bukkit.XUPWUP.LightVote.LightVote
version: 1.5

fixed the problem
