what did i do wrong?

 

You need a plugin.yml file in your /src folder.

 

should be version: 1.00

 

oh i forgot the plugin.yml in the /src folder it was in the .jar though(note plugin.txt is the same as my plugin.yml renamed for easy uplading)

 

You're missing a colon in the last key-value pair.

 

oh thank you

Let's look at the exception:

Code:

java.lang.ArrayIndexOutOfBoundsException: 0
        at com.bukkit.matt123.fakemessage.FmPlayerListener.onPlayerCommand(FmPlayerListener.java:23)

This means that you attempted to access the first element of an array that contained no elements. We know the array contained no elements because the ArrayIndexOutOfBoundsException reports that index 0 was out of bounds.

Let's look at the code in FmPlayerListener:

Code:

String[] split = event.getMessage().split(".");
Player player =event.getPlayer();
if (split[0].equalsIgnoreCase("/fm")) { // <-- Line #23
    player.setDisplayName(split[1]);
    event.setPlayer(player);
    event.setMessage(split[2]);
}

Based upon the exception and the code at line 23 we must assert that the message contained no characters. We know this because the one-argument split method excludes trailing empty strings from the result. You can read this for yourself here: http://download.oracle.com/javase/1.4.2/docs/api/java/lang/String.html#split(java.lang.String)

I would suggest changing your code to something like the following:

Code:

public void onPlayerCommand(PlayerChatEvent event) {
    final String[] split = event.getMessage().split(".");
    final Player player = event.getPlayer();
    // The length needs to be one more than the
    // highest index into the array you need to
    // access.  Since you use index 0, 1, and 2, you
    // must make certain length is at least 3.
    if (split.length >= 3 && split[0].equalsIgnoreCase("/fm")) {
        player.setDisplayName(split[1]);
        event.setPlayer(player); // Not sure what this will do.
        event.setMessage(split[2]); // Not sure what this will do either.
    }
}
