我有一個問題與maven。我寫了一個運行在我的想法中的java代碼。然後我使用mvn包來構建一個jar。仍然沒有問題。ClassNotFoundException：org.apache.log4j.Logger
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger
at infra.Main.main(Main.java:53)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger

有人能幫助新手和我一樣：但薩姆的原因，當我嘗試執行的jar的maven創建我有這樣的錯誤，我不明白？
下面是Java代碼的開頭：
package infra;
import org.apache.log4j.Logger;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import javax.net.ssl.HttpsURLConnection;

import java.net.Proxy;
import java.net.URL;
import java.security.GeneralSecurityException;
import java.security.cert.X509Certificate;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Scanner;
public class Main {
private static String companyName = "lolilol";
private static String baseUrl = "https://" + companyName + ".inspirecloud.net";
private static String loginApi = "/api/publish/Users/Login";
private static String loginUrl = baseUrl + loginApi;
private static String fetchBatchesApi = "/api/query/Messenger/ListBatchesQueryByUploadTime";
private static String fetchBatchesUrl = baseUrl + fetchBatchesApi;
private static String detailBatcheApi = "/api/query/Messenger/ReportQuery";
private static String detailBatcheUrl = baseUrl + detailBatcheApi;
private static Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.local.fr", 8080));
private static int nbEssais = 4;
private static String header = "nbClic;Email;Id;Name;Customer;CompanyName;LastUploadTime;Type;MessageType;EmailId;ToEmailAdr;SendindState;Delivered;DeliveryError;FirstView;LastView;ViewCount;Unsubscribe;ServiceUsed;CustomerId;UrlLandingPage;GMC1;GMC2;GMC3;GMC4;GMC5;\n";
private static Logger logger = Logger.getLogger(Main.class);
public static void main(String[] args) {
logger.info("Début des logs");
HttpsURLConnection loginCon = null;
HttpsURLConnection fetchBatchCon = null;
HttpsURLConnection detailBatchCon;
FileOutputStream fos = null;
Scanner ficIn = null;
int retry;
String email;
String password;
String type;
String from;
String to;
String cookie = null;
String lineIn;
String[] params;
ArrayList<String> messagesMail = new ArrayList<String>();
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
try
{
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (GeneralSecurityException e) {
logger.error("Problème sécurité");
}
然後這裏是pom.xml中：

如果您需要更多的信息可以隨意問。謝謝大家。
你怎麼_execute_你的罐子，你指定的類路徑運行時你的庫？ – epoch
我試圖用兩種不同的方式來執行jar。首先，我只需雙擊它，但沒有發生。然後我在bat文件中使用命令java -jar nameofmyjar.jar – pipouloukou
