java.lang.ExceptionInInitializerError原因：java.util.MissingResourceException：在maven创建的JAR文件中

问题描述

我需要在项目中使用i18n。这是我的项目树。

我用Maven建造两个罐子。这是我的pom.xml

当我在Idea中启动服务器和客户端应用程序时，它运行良好。但是当我构建jar并尝试执行服务器时，我收到一条消息

Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.util.MissingResourceException: Can't find bundle for base name locals,locale ru
        at java.util.ResourceBundle.throwMissingResourceException(UnkNown Source)
        at java.util.ResourceBundle.getBundleImpl(UnkNown Source)
        at java.util.ResourceBundle.getBundle(UnkNown Source)
        at com.itmo.utils.LocaleClass.<init>(LocaleClass.java:14)
        at com.itmo.server.ServerMain.<clinit>(ServerMain.java:11)

这是我的LocaleClass，可用于更改语言并获取要使用的字符串。

import lombok.Getter;

import java.util.Locale;
import java.util.ResourceBundle;

public class LocaleClass {
    @Getter
    public ResourceBundle resourceBundle;

    public LocaleClass(){
         resourceBundle = ResourceBundle
                .getBundle("locals",Locale.forLanguageTag("RU"),new UTF8Control());
    }

    public LocaleClass(ResourceBundle resourceBundle) {
        this.resourceBundle = resourceBundle;
    }

    public void changeLocale(Locale locale){
        resourceBundle = ResourceBundle
                .getBundle("locals",locale,new UTF8Control());
    }

    public enum SupportedLanguages{
        RU,EST,SPA,SWE
    }


    public void changeLocaleByTag(String TAG){
        changeLocale(Locale.forLanguageTag(TAG));
    }
    public void changeLocaleByTag(SupportedLanguages TAG){
        changeLocale(Locale.forLanguageTag(TAG.toString()));
    }

    public String getString(String text){
        return resourceBundle.getString(text);
    }
}

我不太擅长Maven和语言环境，甚至在使用谷歌搜索之后，我也不知道如何解决此问题。
