xoá 2 cái này thử:

if(!configf.exists()) {
configf.getParentFile().mkdirs();
saveResource("config.yml", false);
}
if(!worldcupf.exists()) {
worldcupf.getParentFile().mkdirs();
saveResource("worldcup.yml", false);
}

xóa r thì file config ko load và vẫn còn lỗi đó
 
if(!configf.exists()) {
configf.createNewFile()
}
if(!worldcupf.exists()) {
worldcupf.createNewFile()
}

getWorldCup() ở bên Main.java viết tắt là main.getWorldCup()

private static Main main;

public WorldCup(Main worldcup) {
this.main = worldcup;
}
nói cho biết getWorldCup() ở đâu !
