FileHandler 创建给出 NoSuchFileException 导致 missing.lck

Question

im searching for 2 hours now fo a solution to this:

Im trying to add a FileHandler to a Logger in a JAR. The Log-Directory is outside.

In my IDE (NetBeans) this works:

public static void addFileHandler(Logger logger) {
        try {
            Path p = Paths.get("logs", logger.getName().substring(logger.getName().lastIndexOf('.') + 1) + ".log");
            FileHandler fh = new FileHandler(p.toString(), false);
            fh.setFormatter(sf);
            fh.setLevel(Level.ALL);
            fh.setEncoding("UTF-8");
            logger.addHandler(fh);
            if (errorHandler != null) {
                logger.addHandler(errorHandler);
            }
            if (allHandler != null) {
                logger.addHandler(allHandler);
            }
        } catch (IOException | SecurityException ex) {
            LOG.log(Level.SEVERE, getString("ERROR WHILE ADDING FILEHANDLER TO LOGGER") + " " + logger.getName(), ex);
            return;
        }
        LOG.log(Level.INFO, getString("LOGGER {0} GOT ADDED HIS FILEHANDLERS SUCCESSFULLY") + "!", logger.getName());
    }

But in my Jar i keep getting this for every Logger:

Of course the.lck doesnt exist, the Handler gets created right now...

Same error if i use p.normalize().toAbsolutPath() . I cant use a Stream, cause its the creation of a FileHandler... Like mentioned in any Solution i found...

Why does this happen? How to prevent this?

Answer 1

Well... Thanks VGR...

i just added this right before the FileHandler Initialisation.. now it works wevery time.. I maybe was just stupid, thinking the directory was created before from the FileHandler not the IDE.

if (!Files.exists(p.getParent())) {
            Files.createDirectory(p.getParent());
}
