Can't load my plugin in the server

Sponge Sponge Support

Note: spongePrivate is the name of my plugin.
When i’m trying to start the server i have this error :
[Server thread/ERROR] [Sponge] : Could not pass FMLServerStartedEvent to org.spongepowerd.mod.plugin.SpongeModPluginContainer@b6b6ad0 Java.lang.NullPointerException at me.pogo.spongeprivate.SpongePrivate.onServerStart

And here’s the function onServerStart:

@Listener public void onServerStart(GameInitializationEvent e) { getLogger().info("[SPONGE PRIVATE] Starting the server..."); getCommandManager().register(this, helloWorldSpec, "helloworld", "hello", "test"); getCommandManager().register(this, giveRandomDiamantSpec); }

getLogger() or getCommandManager() or both return null, please post your whole code or we can’t help you

`
@Plugin(id = “me.pogo.spongeprivate”, name = “Sponge Private”, version = “0.0.1”)

public class spongePrivate {

@Listener
public void onServerStart(GameInitializationEvent e) {
    getLogger().info("[SPONGE PRIVATE] Demarrage du plugin en cours...");
    getCommandManager().register(this, helloWorldSpec, "helloworld", "hello", "test");
    getCommandManager().register(this, giveRandomDiamantSpec);
}



private static Logger logger;

@Inject
public static void setLogger(Logger logger) {
    logger = logger;
}

public static Logger getLogger() {
    return logger;
}

            .permission("spongePrivate.cmd.giveRandomDiamant")
            .executor(inst_giveRandomDiamant)
            .build();

}

You need to initialize the logger:

@Listener
public void onPreInit(GamePreInitializationEvent event) {
        MyPluginClass.logger = LoggerFactory.getLogger('plugin-name');
}

logger = logger

This does not work. When a method argument has the same name as a member variable, the variable name only refers to the method argument. Change to this:
this.logger = logger

False. As you can see, it is @Injected.
In fact, I’ve never heard of anyone doing that; if the mere sight of @Inject sends you into a gibbering fit, most people settle for getting the PluginContainer from the PluginManager, and getting the Logger from that.
