Der Command ist in der plugin.yml und in der Main eingetragen. Eclipse selber erkennt auch keinen Fehler

Eclipse selber erkennt auch keinen Fehler

Es handelt sich ja auch um einen Laufzeitfehler. Bei einer NullPointerException erfolgt ein Zugriff auf ein Objekt, welches nicht existiert. Schau in die angegebene Zeile:

at de.name.plugin.main.Main.onEnable(Main.java:25

und prüfe, was dort zur Laufzeit den Wert null haben könnte.

Ich hab ein kleines Problem bei meinem Spigot Plugin:

Ich verstehe aber nicht wieso. Ich möchte doch Abfragen ob dieser Eintrag in der config nicht vorhanden ist sprich null um ihn dann einen Wert zuteilen zu können

Wenn das nicht geht wie kann ich das sonst machen?

Error occurred while enabling Till v1.1 (Is it up to date?) java.lang.NullPointerException: null? Was ist eine NullPointerException? Wie löse ich das Problem?

Hallo ich habe einen kleinen Command geschrieben der mir ein Item gibt.

So habe ich ihn registriert:

public class Till extends JavaPlugin {
    @Override
    public void onEnable() {
                getLogger().info("Plugin Loaded");
                getCommand("test").setExecutor(new TillTestCommand());

Er hat immer gut funktioniert und auch jetzt noch.

Dann habe ich mit einen Plugin Manager einen JoinQuitListener und andere Events hinzugefügt. Sie funktionierten auch soweit.

Als ich dann ein neuen Command hinzufügte:

public class Till extends JavaPlugin {
    @Override
    public void onEnable() {
                getLogger().info("Plugin Loaded");
                getCommand("test").setExecutor(new TillTestCommand());
                getCommand("adminItems").setExecutor(new AdminItemsCommands());

Funktionierte nur noch der "TillTestCommand"

Die Events funktionierten nicht mehr und auch der dazugekommene Command funktionierte nicht.

Es gab beim Start des Servers eben eine Fehlermeldung die ich gegoogelt habe aber andere Foren und Beiträge halfen mir nicht weiter.

Die ganze Meldung:

[12:40:46] [Server thread/INFO]: [Till] Loading Till v1.1

[12:40:46] [Server thread/INFO]: [Till] Enabling Till v1.1

[12:40:46] [Server thread/INFO]: [Till] Plugin Loaded

at org.bukkit.plugin.java.JavaPlugin.setEnabled(JavaPlugin.java:263) ~[spigot.jar:git-Spigot-800b93f-8160e29]

Ich glaube das weitere ist nicht wichtig!

Vielen Dank schonmal!

[Spigot 1.17] Methode aus anderer Klasse verwenden?

Aktueller Code:

package Main;
public class API {
    public static API instance;
    public API(){
        instance = this;
    }
    public static API getInstance(){
        return instance;
    }
    public String getAPI(){
        return "§cThis is an API";
    }
}

In onEnable(){}:

API.getInstance().getAPI();

Fehler:

Error occurred while enabling ActionBarTimer v1.0 (Is it up to date?)

java.lang.NullPointerException: Cannot invoke "Main.API.getAPI()" because the return value of "Main.API.getInstance()" is null

Wie kann ich die Methode richtig aufrufen und warum sagt mir die Konsole was von null?

Und wie heißt das fachsprachlich, dass wenn man Methoden aus anderen Klassen verwendet?

Danke :)

Hey, mein Minecraft server startet ab und zu nicht mehr. Ich habe einen Linux Root server, auf dem nur der eine server läuft. Trotzdem bekomme ich immer diese Error meldung. Was kann ich tun außer Java zu killen und es erneut zu versuchen.

Ich starte immer eine start.sh in der folgender text steht

java -jar spigot.jar

Das klappt auch manchmal nur die anderen male kommt immer dieser error:
