Errors on startup - SOLVED (Noob mistake) :P

Hi all,

To start off with, i did do some reasearch about this problem but came up empty handed.

That aside, I recently made a small plugin for my server that i am on to stop griefers. It has no errors in the code or in the YML.

It was made with the 1.0.1 RB and JRE6 and the server is using the same.

What is this error and how can it be fixed?

Code:

2011-12-25 16:22:48 [SEVERE] Error occurred while enabling StopTheGriefer v0.7 (Is it up to date?): null

What's line 33 in your main class say? Most likely it's a command that you forgot to add to plugin.yml, but show me that line anyway.

 

Code:java

    public void onEnable() {
        PluginManager pm = this.getServer().getPluginManager();
        log.info(pdfFile.getName() + " has been enabled with version " + pdfFile.getVersion()); /* Line 33 */
        pm.registerEvent(Event.Type.BLOCK_PLACE, this.blockListener, Priority.Normal, this);
    }
 

 

EDIT: Nevermind.

Did you declare your pdffile before onEnable? you should declare 'public PluginDescriptionFile pdffile;' at the top, and then in onEnable(), you declare pdffile = getDescription().

 

Nevermind sorry, i had it as;

Code:java

 
public class StopTheGriefer extends JavaPlugin {
 
    PluginDescriptionFile pdfFile = this.getDescription();
 
    Logger log = Logger.getLogger("Minecraft");
 
    private final StopTheGrieferBlockListener blockListener = new StopTheGrieferBlockListener(this);
 
    public ArrayList<String> ActivePlayers = new ArrayList<String>();
 
 
 
    public void onEnable() {
        PluginManager pm = this.getServer().getPluginManager();
        log.info(pdfFile.getName() + " has been enabled with version " + pdfFile.getVersion());
        pm.registerEvent(Event.Type.BLOCK_PLACE, this.blockListener, Priority.Normal, this);
    }
 
    public void onDisable() {
        log.info(pdfFile.getName() + " has been disbaled");
    }
 

instead of

Code:java

 
public class StopTheGriefer extends JavaPlugin {
 
 
 
    Logger log = Logger.getLogger("Minecraft");
 
    private final StopTheGrieferBlockListener blockListener = new StopTheGrieferBlockListener(this);
 
    public ArrayList<String> ActivePlayers = new ArrayList<String>();
 
 
 
    public void onEnable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        PluginManager pm = this.getServer().getPluginManager();
        log.info(pdfFile.getName() + " has been enabled with version " + pdfFile.getVersion());
        pm.registerEvent(Event.Type.BLOCK_PLACE, this.blockListener, Priority.Normal, this);
    }
 
    public void onDisable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        log.info(pdfFile.getName() + " has been disbaled");
    }
 

Nooby mistake :S

 

Yea that'll about do it for you
