Fix that main code block and I'm sure we can help you better.

In the error I see:
Caused by: java.lang.ClassNotFoundException: com.Cmurphy.bukkit.bukkitPlugin

You probably have to change your yml file so it is com.Cmurphy.bukkit.bukkitPlugin.bukkitPlugin

 

The template isn't up-to-date.

You need to change some imports and the plugin constructor. But Eclipse or any other IDE should mark the relevant lines in the source code.

org.bukkit.Player -> org.bukkit.entity.Player
org.bukkit.Block -> org.bukkit.block.Block
org.bukkit.BlockFace -> org.bukkit.block.BlockFace

Code:

public <pluginname>(PluginLoader pluginLoader, Server instance, PluginDescriptionFile desc, File plugin, ClassLoader cLoader) {
        super(pluginLoader, instance, desc, plugin, cLoader);

needs a change to

Code:

public <pluginname> (PluginLoader pluginLoader, Server instance, PluginDescriptionFile desc, File folder, File plugin, ClassLoader cLoader) {
        super(pluginLoader, instance, desc, folder, plugin, cLoader);
     

And also in the plugin.yml you need to change the main value:
com.mysticx.bukkit.backupplugin.BackupPlugin instead of com.bukkit.mysticx.backupplugin (for example)

 

Changed the yml file, got this

Code:

Thanks in Advance.

 

bukkit tries to load com.sharpiedew.bukkit.sample.SamplePlugin while it should load com.sharpiedew.bukkit.sampleplugin.sampleplugin.SamplePlugin.

You need to fix your main: line in the plugin.yml! Thats why I asked you to post it

plugin.yml

Code:

name: Sample Plugin
main: com.sharpiedew.bukkit.sampleplugin.sample.SamplePlugin
version: 0.0.1

I have tried several variations of the main code and no luck.. Please Help

 

It would be "com.bukkit.sharpiedew.SamplePlugin.SamplePlugin". I just had this same problem and fixed it like this. It's your main plugin name (In this case, SamplePlugin) right after the line in your package statement.

 

Exactly, and thats basically the same thing I told you. But you changed your package structure..
