Seems like so, his previous thread was asking him how to start on Bukkit plugins because he has little Java knowledge.

OP (or @Viniccius007), could you post your code on the thread? It sounds like one of your vital constructors were either private/invalid.

 

kkk, ok,but I do nothing in code only that:

package com.viniccius007.colorinfo;

import org.bukkit.plugin.java.JavaPlugin;

class Main extends JavaPlugin {

public void onLoad() {
getLogger().info("§4Plugin load");
}
public void onEnable() {
getLogger().info("§4Plugin enable");
}
public void onDisable() {
getLogger().info("§4Plugin disabled");
}
}

plugin.yml:
name: colorinfo
version: 1.0
main: com.viniccius007.colorinfo.Main

 

@Viniccius007
You do not need to log your own plugins. Bukkit does this for you.

You forgot to make your "Main" class public. Add the public modifier before Main to fix this issue.
