Sample Plugin doesn't work!

Hello Community,

today i created my first plugin.
I downloaded Eclipse ,the Bukkit API and the Generator from the tutorial in the wiki.
I created my application with the Generator and linked the Bukkit API to my project.

I get this error from Eclipse:
The constructor JavaPlugin(PluginLoader, Server, PluginDescriptionFile, File, File, ClassLoader) is undefined

I am a noob at programming with the Bukkit API.
Next step I export the project to a jar file but CraftBukkit fires some errors:

had the same problem... (I might still have co-developer isnt online so i ask him if he fixed it)
would be great for new commers if somebody would fix teh sample plugin....

 

Can someone give me sample code for a plugin that works?

 

Just made a blank plugin. The only thing you have to do is change the location of the external bukkit/craftbukkit jars.

 

I used your code in BlankZip and Eclipse didn't fired errors again, but craftbukkit fired this erros:

Here is my plugin if you would like to test it on your server: <Edit by Moderator: Redacted mediafire url>

 

I've had a lot of success using this example (which is also linked on the wiki tutorial):
https://github.com/Bukkit/SamplePlugin/tree/master/src/main/java/com/dinnerbone/bukkit/sample

That said, I think these are meant to be templates for a plugin, not ready to bake files. (though they probably build fine)

What I've found to be more useful is to peruse the plugin releases section, or the plugin list for authors who post their source code, and read through that. I find them to be much more helpful than a blank template, since you can see how things are done practically.

 

Okay thanks for the tips.

I fixed the error with editing this in plugin.yml:
main: com.bukkit.Ninjasturm.Gildenmeister.Gildenmeister

I added the class at the end of the line.
