Still can't write to files.

I've been working for days trying to figure this out. No matter what I do, no matter what code I write, it simply won't write to the files. I've literally done everything that I can think of, and the files still remain blank after forcing them to be written in. Here is my code:

Code:

    public void writeGuests(){
        File f = new File("plugins/Origins/groups/guests.txt");
        try {
            FileWriter fw = new FileWriter(f, true);
            BufferedWriter bw = new BufferedWriter(fw);
            f.delete();
            f.createNewFile();
            for(String str : plugin.members){
                bw.append(str + "\r\n");
            }
            bw.close();
        }
        catch(Exception e){
            plugin.log.info(plugin.name + "Error writing to guests.txt");
        }
    }

This is but the latest revision among several dozens of other revisions where I tried to get this to work. There doesn't seem to be any errors from the console, so I honestly don't understand why it doesn't write.

 

Why don't you use Bukkit's config file system?

 

Because it's derpy. The YML config system frequently derps and deletes everything in the file. Txt files don't do that. I appreciate the thought, but I'm not looking for even worse code.

 

Oh well ive never worked with config files... So I cannot help.

 

It's not the config files. I just need to figure out why this isn't writing to files.

 

@Razorcane
are you on windows or *nix
file paths use different characters, make sure your using the right one.
or just append File.seperator

EDIT:
and for the record, the yml parser and writer does not understand in line comments, but if comments are at the top of the file, it will respect it.

 

Basic assumptions: is the current working directory where you think it is? Check if the subdirectories you think are there, are really there.

I have never had the config system delete or empty out stuff. None of my plugins or hundreds of others out there in the marketplace. It's not derpy, there's probably a simple mistake made somewhere.

While I won't dissuade anyone from using File.separator, the ONLY part of Windows which demands a backslash is the command line interpreter CMD.EXE - all of the Windows file APIs accept the forward slash, just like Linux and Unix and OSX. Try it sometime; this is true in Java or C++ or Perl or Python. If you ever have to support Mac OS9 or VAX VMS, then you need to pay attention.

 

I'm using Windows, but the problem is it doesn't write at all.

I would just prefer txt files. I don't see why it's a problem that I want to use txt files. And yes, it's in the proper directory. The console doesn't report any exceptions or errors when I call the methods, they just don't write. At first I thought it was because my computer didn't have the proper write permissions, but it does. So I don't really understand why it's doing this.

 

I am afraid to say I am having the EXACT SAME PROBLEM. EXACT. I set up an onPlayerJoin() method to write out the player name and IP in a text file, and it won't freaking generate!

Code? Here.

    public static String getDate() {
        Calendar c = Calendar.getInstance();
        int month = c.get(2) + 1;
        String date = Integer.toString(month);
        date = date + "/";
        date = date + c.get(5) + "/";
        date = date + c.get(1) + " ";
        date = date + c.get(11) + ":";
        date = date + c.get(12) + ".";
        date = date + c.get(13);
        return date;
    }
}

Anyone? This needs to be fixed
