Can't send colored(or any) messages to console in onEnable() with ConsoleSender?

Title is self-explanatory. I can't seem to get my plugin to send the console a message at all, colored or not. Here is my code, snipped a bit to hide the goods(the package and imports are in working order):

Code:java

public class Main extends JavaPlugin implements Listener {
    public static Main plugin;
    public final static Logger logger = Logger.getLogger("Minecraft");
 
    public void LoginListener(Main JavaPlugin) {
        getServer().getPluginManager().registerEvents(this, plugin);
    }
    @Override
    public void onDisable() {PluginDescriptionFile pdffile = this.getDescription();
        logger.info(pdffile.getName() + " v" + pdffile.getVersion() + " is now disabled.");
    }
    @Override
    public void onEnable() {PluginDescriptionFile pdffile = this.getDescription();
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        boolean sentAMsg = sendConsoleAMsg(ChatColor.DARK_RED + "Test with color");
        logger.info("--------------------------------------------------------------------");
        logger.info("Message function returned: " + sentAMsg);
        logger.info("--------------------------------------------------------------------");
        boolean sentAMsg = sendConsoleAMsg("Test without color");
        logger.info("--------------------------------------------------------------------");
        logger.info("Second message returned: " + sentAMsg);
        logger.info("--------------------------------------------------------------------");
    }
    public static boolean sendConsoleAMsg(String msg) {
        try {
            Bukkit.getServer().getConsoleSender().sendMessage(msg);
            return true;
        } catch (NullPointerException e) {
            FileMgmt.LogCrash(e, e.getMessage(), false);
        }
        return false;
    }
}

I CAN, however, use

Code:java

sendConsoleAMsg(ChatColor.DARK_RED + "Hello, world!");

in any other event or function/method. So why can't I use this in onEnable()?

 

Try just:

Code:java

this.getLogger().info(ChatColor.RED + "Color test.");

 

That just prints the message in white with funny characters, and I can't install anything that changes the way cmd.exe runs. Any other ideas?

 

The Console Logger is not able to accept ChatColor input. You can only add ChatColor to CommandSender.sendMessage(), which is accessible via onCommand() and through getServer().

So in your Plugin class you can call:

Code:java

 
this.getServer().getConsoleSender().sendMessage(message)
 

The only downside to this is (as far as I'm aware), it will not write a message in the log file. It will only print it to the Console.

EDIT: I didn't read that part x3 Seems you figured that out on your own

 

That code raises a null pointer exception:

Code:

13:33:15 [SEVERE] Error occurred while enabling EnteisAutoBroadcast v4.5 (Is it up to date?)

That's why I made the sendConsoleAMsg function to handle null pointer exceptions. I have no idea why it throws a nullPointerException, it just does. The line you provided is on line 122.

 

maybe the console isn't set up yet when the server is starting

 

Brian_Entei
And which is line 122 ? Because your posted code only has 33 lines.

 

ferrybig, That's probably why, but then how the heck do other plugins log colored messages while my server starts? BattleArena does this for sure, and I just would like to know how to too.

Digi, I said before that I cut all the goods out of the code I posted, I was saying that

Code:java

this.getServer().getConsoleSender().sendMessage(ChatColor.DARK_RED + "Color test");

was on line 122.

Brian_Entei
Well... that posted code has alot of other issues and syntax errors... so this is why I ask: is that code used in your main class which is linked in the plugin.yml ?

Because if you extend JavaPlugin in another class that is NOT the main class then your getServer() method for example will return null, you have to pass the plugin instance over to use stuff from the main class.

And this code:

Code:

this.getServer().getConsoleSender().sendMessage(ChatColor.DARK_RED + "Color test");

...placed in onEnable() from a main class works properly, I've just tested it.

 

Well, the code I use getConsoleSender() in is linked in the plugin.yml, BUT, do you have

Code:

load: STARTUP

in your plugin.yml? I think that's why I get the exception. And what syntax errors? The code runs smoothly.

Also, if a class isn't the one specified in the plugin.yml, then DON'T make it extend JavaPlugin? Is that what you meant? If so, thanks, I didn't know that.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Brian_Entei
I've also tested by using it in onLoad() (which is triggered before onEnable) along with load: STARTUP, it works just fine!
And yes, that's what I meant, only the main class (that is linked in plugin.yml) should extend JavaPlugin, any other class extending that would be broken.

 

Well, no matter what I try, I always get the nullpointerexception that I posted above, so I'll copy my onEnable() function and the other functions related to it that are in the error(which I'm posting a fresh copy of here too).

Oh, and if you see a way I can do something in the code I posted simpler or better, feel free to comment about it, I will gladly accept help!

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Personally, I would create a function like "debug(String message)" function that will check if showDebugMessages is enabled, rather than using a if for each debug message.

 

Brian_Entei
Your 'console' field is not asigned, it's still null.

Just use Bukkit.getConsoleSender() directly instead of storing so many things.

 

socram8888 Do you mean like this?

Code:java

sendDebugMsg(String message);

That would tale a lot of ifs out of the equation. Thanks! Oh, and Digi If I do that, then it throws the error I posted for that line, even if I don't have load: STARTUP set in the plugin.yml, but maybe I've fixed it, so when I get home, I'll try it anyway, so thanks.

 

Brian_Entei
You need to asign it in onEnable() if you really want to use a field... but like I said, it would be better to use it directly where you need it.

 

I know this thread is a little old but looking for a similar answer I was hoping to find it here quickly through google links but did not. So I believe this following is a quick solution to having color in your console.
Server.log will log following but the ansi color codes appear not the color.

Enter the following shortcut vars to your main class,

Code:java

 // console coloring made easy
public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_BLACK = "\u001B[30m";
public static final String ANSI_RED = "\u001B[31m";
public static final String ANSI_GREEN = "\u001B[32m";
public static final String ANSI_YELLOW = "\u001B[33m";
public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";
public static final String ANSI_BOLD = "\u001B[1m";

Now when you want to send color to console with lets say your onEnable...
use something like this,

Code:java

getLogger().info("["+ ANSI_CYAN + "MyPluginName" + ANSI_RESET +"]" + ANSI_GREEN +" has been Enabled." + ANSI_RESET);

*edit: removed this.myLogger, replaced with getLogger()

(ref) ANSI color codes

 

RROD

THANK YOU!

 

Intravenous wow, I was also looking for that! I'll try it out as soon as possible!

EDIT: Doesn't seem to work on Windows 7 32 bit or 64 bit... maybe the ANSI codes are for other platforms?
