Question

我在IntelliJ工作，我试图重命名我的项目！这样做，并重命名一切，我相信我做的正确，我实际上无法启动我的应用程序。

错误：

错误指向我的Config类，但是我不确定原因：

public class Config {
    private MochaMessages instance = MochaMessages.getInstance();
    private FileConfiguration config = instance.getConfig();

    public Config() {
    }

    public String get(String node) {
        System.out.println("Fetching: " + node);
        return config.getString(node);
    }

    public void set(String node, String value) {
        config.set(node, value);
    }

    public boolean getBoolean(String node) {
        System.out.println("Fetching: " + node);
        return config.getBoolean(node);
    }

}

通过我的MochaMessages类调用哪个：这是相关的方法：

private static MochaMessages instance;
private Config config = new Config();
public void onEnable() {
    instance = this;
    createConfig();
    te = getTokenEnchant();
    if (!config.getBoolean("database.enabled")) {
        disablePlugin("Enable MySQL!");
    } else if (config.get("mocha.currency").equalsIgnoreCase("TokenEnchant")) {
        if (te == null) {
            disablePlugin("Unable to access TokenEnchant. Disabling Plugin!");
        }
    } else {
        Bukkit.getServer().getPluginManager().registerEvents(new MochaListener(), this);
        new MochaModel().createTable();
        new CommandHandler();
    }
}

我相信这是因为实例返回null，即使它不应该。这在重命名之前完美无缺！

发生了什么事？
