Spigot Welcome Message 1.0.3

Im guessing you are new to coding plugins.

 

You should store the message as a list in your config:

Code (Text):

config.addDefault("join_message", Arrays.asList(new String[] { "line 1", "line 2", "line 3"}));

Then you just iterate through the list and send each line with a for loop:

Code (Text):

for (String line : getConfig().getStringList("join_message") {
    player.sendMessage(line);
}

This allows unlimited lines instead of your hardcoded 6.
