New Version Message

Here is a quick tutorial on how to tell the admins there is a new update available for you plugin

add this boolean to you main class

Code:java

public boolean updates = false;

add this to the onEnable

Code:java

checkVersion("Version: " + getDescription().getVersion());

Now Create the checkVersion Method

Code:java

public void checkVersion(String s){
 
try {
URL url = new URL("[url]http://your-domain.com/your-file.html[/url]");
 
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null) {
if(str.equals(s)){
updates = false;
log.info("[your plugin] No Updates!");
}else{
updates = true;
log.info("[your plugin] Newer version is Available! " + str);
}
}
 
in.close();
 
 
 
} catch (IOException e) {
e.printStackTrace();
}
 
}

now to broadcast the message to the ops and admins create a PlayerJoinEvent

Code:java

@EventHandler()
public void join(PlayerJoinEvent event){
Player p = event.getPlayer();
if(p.hasPermission("some.permission") || p.isOp()){
if(updates == true){
p.sendMessage("There is a newer version of <your plugin> available for download!");
}else{
p.sendMessage("<your plugin> is up to date!");
}
}
}

now to create the html file and upload it to your website

Code:

Version: 1.0

Hope this helped!

 

Why is the String in your URL object wrapped in BBCode URL tags lol.

Also, just a suggestion and nothing major. I'd recommend not storing the version in a format like "Version: 1.0", but rather something simple like "1.0". That allows you to easily perform inequality operations on it (after parseDoubling it of course) which is much better (imo) than just checking if it's not equal. Like i said, its a small detail but it can be useful.

Nice resource.

 

they can change that its just that way i did it lol and i have no ide why its

edit: the url tags wont go away

 

is there an version that works whit bukkit dev whit this?

 

ferrybig AutoUpdate not only uses bukitdev but also makes (semi)automated updates possible and has many other features like multithreading (no in-game lag cause of slow network I/O), updating all plugins (using it) with one command, ...

 

hyyym. this method still work?
I have a error in console at
checkVersion("Version: " + getDescription().getVersion());
Null pointer exception.

Hyyym. I find error and work. but I have many lines in console from:
log.info("[your plugin] Newer version is Available! " + str);

Maybe is from hosting? because is full of html staff. center blah blah
