Issue with api

[Conutik]

I'm trying to use the TAB Api with my plugin but I keep getting this error when trying to load:

org.bukkit.plugin.InvalidPluginException: java.lang.NullPointerException: Cannot invoke "me.neznamy.tab.api.TabAPI.getTeamManager()" because the return value of "me.neznamy.tab.api.TabAPI.getInstance()" is null

I tried setting TAB as softdepend and depend but nothing changed. My Code:

public class Main extends JavaPlugin implements Listener {
    TabAPI TABInstance = TabAPI.getInstance();
    TeamManager teamManager = TabAPI.getInstance().getTeamManager();
    @Override
    public void onEnable() {
        new BukkitRunnable() {
            @Override
            public void run() {
                for (Player p : Bukkit.getOnlinePlayers()) {
                    for (Player ps : Bukkit.getOnlinePlayers()) {
                        if (Functions.blockBetweenPlayers(p, ps)) {
                            teamManager.hideNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.hideNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        } else {
                            teamManager.showNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.showNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        }
                    }

                }
            }
        }.runTaskTimer(this, 0, getConfig().getInt("update_period"));

        Bukkit.getPluginManager().registerEvents(this, this);
        Bukkit.getServer().getConsoleSender().sendMessage(ChatColor.GREEN + "VTags is now working");
    }
}

TAB is downloaded on my server, and I have it as a dependency. (Using spigot/paper for 1.17.1)

[NEZNAMY]

API was null. That means you either shaded the plugin's classes into your jar or your code ran before TAB loaded.

[Conutik]

Ok So I fixed that issue now, so it runs after TAB Loaded. But I'm still getting the issue.

My Code:

    TabAPI TABInstance;
    TeamManager teamManager;
    @Override
    public void onEnable() {
        new BukkitRunnable() {
            @Override
            public void run() {
                TABInstance = TabAPI.getInstance();
                teamManager = TabAPI.getInstance().getTeamManager();
                for (Player p : Bukkit.getOnlinePlayers()) {
                    for (Player ps : Bukkit.getOnlinePlayers()) {
                        if (Functions.blockBetweenPlayers(p, ps)) {
                            teamManager.hideNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.hideNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        } else {
                            teamManager.showNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.showNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        }
                    }

                }
            }
        }.runTaskTimer(this, 0, getConfig().getInt("update_period"));

        Bukkit.getPluginManager().registerEvents(this, this);
        Bukkit.getServer().getConsoleSender().sendMessage(ChatColor.GREEN + "VTags is now working");
    }
}```

Send full console log. Null API means the plugin is not enabled.

Just checked, the plugin (TAB) is enabled

[NEZNAMY]

Random stack trace won't help me at all. I have no idea what is on line 21 of your main class. Send full console log.

[Conutik]

That's the full log in console.

    TabAPI TABInstance;
    TeamManager teamManager;
    @Override
    public void onEnable() {
        new BukkitRunnable() {
            @Override
            public void run() {
                TABInstance = TabAPI.getInstance();
                teamManager = TabAPI.getInstance().getTeamManager();
                for (Player p : Bukkit.getOnlinePlayers()) {
                    for (Player ps : Bukkit.getOnlinePlayers()) {
                        if (Functions.blockBetweenPlayers(p, ps)) {
                            teamManager.hideNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.hideNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        } else {
                            teamManager.showNametag(TABInstance.getPlayer(p.getUniqueId()), TABInstance.getPlayer(ps.getUniqueId()));
                            teamManager.showNametag(TABInstance.getPlayer(ps.getUniqueId()), TABInstance.getPlayer(p.getUniqueId()));
                        }
                    }

                }
            }
        }.runTaskTimer(this, 0, getConfig().getInt("update_period"));

        Bukkit.getPluginManager().registerEvents(this, this);
        Bukkit.getServer().getConsoleSender().sendMessage(ChatColor.GREEN + "VTags is now working");
    }
}

Starting from line 12 and going up

[NEZNAMY]

The API works. Many are using it. If you refuse to provide requested information I will not help you.

[Conutik]

Where can I find the full log?

[NEZNAMY]

logs/latest.log. If you don't know this, you may not be ready to use API from other plugins.

[Conutik]

No I know but I meant like you want the one before the change or after?

This is the after one: https://www.toptal.com/developers/hastebin/ujepexofuy.sql

[NEZNAMY]

Open your jar and check if it contains tab classes.

[Conutik]

Yes it does

[Conutik]

they are defined and everything,
