            for (String s : children) {

                if (!s.equals("lib")) {

public static boolean deleteDir(File dir) {

        if (dir != null && dir.isDirectory()) {

            String[] children = dir.list();

            for (int i = 0; i < children.length; i++) {

                boolean success = deleteDir(new File(dir, children[i]));

                if (!success) {
