"Invalid plugin.yml" message on enable of Bukkit plugin

I'm working on my first Bukkit plugin. Here's my main class in the eruverio.EruvPlg package:

package eruverio.EruvPlg;

import org.bukkit.plugin.java.JavaPlugin;

public final class main extends JavaPlugin {

}

And here's the plugin.yml:

name: Test
main: eruverio.EruvPlg.main
version: 1.0

When I run exported JAR file on a Bukkit server, it throws an exception:

    [14:09:14] [Server thread/ERROR]: Could not load 'plugins\EruvPlg.jar' in folder 'plugins'

How can I fix this?

Solution

  • The 'plugin.yml' file must be placed in the main folder of the project.
