ClassNotFound exception

Hi,
I'm trying to make a really simple plugin. I am having trouble with the setup.

Code:

Jan 22, 2011 2:06:58 PM org.bukkit.plugin.SimplePluginManager loadPlugins
SEVERE: Could not load plugins\Pmark.jar in plugins: null
org.bukkit.plugin.InvalidPluginException

Here is my code, http://pastebin.com/nNu6n7DJ
I have adapted it from http://forums.bukkit.org/threads/basic-bukkit-plugin-tutorial.1339/
I'm not really sure what's going on. The yml is in place and the code looks like everything needed is imported. They all have the correct package identifiers. Is there a setting for dependencies that I'm missing? Am I exporting the project to a jar incorrectly somehow?

 

The yml file doesn't point to the right place. It has to point to your main plugin file. So from your code, your general package is com.bukkit.Aaron.Pmark, so the "main" line in your yml file would be,
"main: com.bukkit.Aaron.Pmark.Pmark".

 

wow that was so simple. UGH. Thanks!
