Bug 56019

I am using RollingFileAppender with TimeBasedRollingPolicy. I'd like backup files to be saved in a different folder than the current one.

The problem I am having, is that it only works when destination directory of backup files is already created. When backup directory does not exists, then rollover is skipped.

I debugged code and realized that the problem may be solved if the backup folder is created in FileRenameAction

Just change the method execute in FileRenameAction to:

  public static boolean execute(
    final File source, final File destination, boolean renameEmptyFiles) {
    if (renameEmptyFiles || (source.length() > 0)) {
    	File destinationParent = destination.getParentFile();
    	if (!destinationParent.exists()) {
    		destinationParent.mkdirs();
    	}
      return source.renameTo(destination);
    }

    return source.delete();
  }
