无法初始化主类的原因？

在Eclipse中运行Maven“编译”，“安装”命令以创建可执行JAR并继续运行该JAR之后，出现以下错误

Error: Unable to initialize main class org.example.project.StockTracker`
Caused by: java.lang.NoClassDefFoundError: com/mashape/unirest/http/exceptions/UnirestException

我不知道发生了什么事。我该如何解决？以下是更多详细信息。我用主要类信息更新了POM，并将类路径设置为“ true”。

主要类别代码

package org.example.project;

import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;

public class StockTracker {

    public static void main (String[] args) throws UnirestException, InterruptedException  {
        HttpResponse<String> response = Unirest.get("https://apidojo-yahoo-finance-v1.p.rapidapi.com/market/get-quotes?region=US&lang=en&symbols=TSLA")
                    .header("x-rapidapi-host", "apidojo-yahoo-finance-v1.p.rapidapi.com")
                    .header("x-rapidapi-key", "api-key")
                    .asString();

        //System.out.println(response.getBody());
        System.out.println("response.getBody()");
    }
}

UNIREST例外类别代码

package com.mashape.unirest.http.exceptions;

public class UnirestException extends Exception {

    private static final long serialVersionUID = -3714840499934575734L;

    public UnirestException(Exception e) {
        super(e);
    }

    public UnirestException(String msg) {
        super(msg);
    }

}
