Como usar:

// Local do arquivo dentro do projeto.
String localFile = "/resources/example.yml";
// Local da pasta onde será copiado o arquivo.
String toDir = "C:\\kits";
// Nome do arquivo.
String fileName = "kit.yml";

FileCopy fileCopy = new FileCopy(localFile , toDir , fileName);
fileCopy.copy();
