How to resolve the “notempty” error when deleting a folder in log4j2?

When deleting a folder with log4j2, an error “notempty” will be thrown if the folder is not empty. To solve this issue, you can use the following method:

1. Delete a folder using the FileUtils utility class.

import org.apache.commons.io.FileUtils;

public class Log4j2DeleteFolder {
    public static void main(String[] args) {
        try {
            FileUtils.deleteDirectory(new File("path_to_folder"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

1. Delete folders using recursion in Java.

public class Log4j2DeleteFolder {
    public static void main(String[] args) {
        File folder = new File("path_to_folder");
        deleteFolder(folder);
    }

    private static void deleteFolder(File folder) {
        File[] files = folder.listFiles();
        if (files != null) {
            for (File file : files) {
                if (file.isDirectory()) {
                    deleteFolder(file);
                } else {
                    file.delete();
                }
            }
        }
        folder.delete();
    }
}

Both of these methods can be used to delete non-empty folders, but be sure to replace “path_to_folder” with the actual folder path when using them. Also, to avoid accidental deletions, please use these methods to delete folders with caution.
