What is this Java error about for maven on Ubuntu: package org.apache.http.client does not exist import org.apache.http.client.ClientProtocolExcepti?

I am using Java and Maven Project on Ubuntu but I am getting following error upon building Java code on NetBeans IDE: package org.apache.http.client does not exist import org.apache.http.client.ClientProtocolException;

I have following on my Ubuntu:

sudo which java /usr/bin/java sudo echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/>:/snap/bin sudo mvn -version Apache Maven 3.6.3 Maven home: /usr/share/maven Java version: 11.0.17, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64 Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "5.15.0-58-generic", arch: "amd64", family: "unix" sudo echo $JAVA_HOME /usr/lib/jvm/java-1.11.0-openjdk-amd64 sudo java -version openjdk version "11.0.17" 2022-10-18 OpenJDK Runtime Environment (build 11.0.17+8-post-Ubuntu-1ubuntu220.04) OpenJDK 64-Bit Server VM (build 11.0.17+8-post-Ubuntu-1ubuntu220.04, mixed mode, sharing) sudo javac -version javac 11.0.17 which mvn /usr/bin/mvn 

Do I have to include the path of maven or else?

Question Edited to give clear picture:

ant -f /home/kamran/NetBeansProjects -Dnb.internal.action.name=build jar init: Deleting: /home/kamran/NetBeansProjects/build/built-jar.properties deps-jar: Updating property file: /home/kamran/NetBeansProjects/build/built-jar.properties Compiling 89 source files to /home/kamran/NetBeansProjects/build/classes /home/kamran/NetBeansProjects/Multichain API Demo for Students/src/main/java/multichain/command/builders/QueryBuilderCommon.java:14: error: package org.apache.http.client does not exist import org.apache.http.client.ClientProtocolException; /home/kamran/NetBeansProjects/Multichain API Demo for Students/src/main/java/multichain/command/builders/QueryBuilderCommon.java:15: error: package org.apache.http.client.methods does not exist import org.apache.http.client.methods.HttpPost; /home/kamran/NetBeansProjects/Multichain API Demo for Students/src/main/java/multichain/command/builders/QueryBuilderCommon.java:16: error: package org.apache.http.entity does not exist import org.apache.http.entity.StringEntity; /home/kamran/NetBeansProjects/Multichain API Demo for Students/src/main/java/multichain/command/builders/QueryBuilderCommon.java:17: error: package org.apache.http.impl.client does not exist import org.apache.http.impl.client.CloseableHttpClient; 

The error is on following class package import:

/* * Copyright (C) 2017 Worldline, Inc. * * MultiChainJavaAPI code distributed under the GPLv3 license, see COPYING file. * https://github.com/SimplyUb/MultiChainJavaAPI/blob/master/LICENSE * */ package multichain.object.formatters; import java.util.List; import com.google.gson.GsonBuilder; /** * @author Ub - H. MARTEAU * @version 2.1 */ public class GsonFormatters { protected static String formatJson(String[] values) { final GsonBuilder builder = new GsonBuilder(); final Gson gson = builder.create(); return gson.toJson(values); } protected static String formatJson(List<Object> values) { final GsonBuilder builder = new GsonBuilder(); final Gson gson = builder.create(); return gson.toJson(values); } protected static String formatJson(Object value) { final GsonBuilder builder = new GsonBuilder(); final Gson gson = builder.create(); return gson.toJson(value); } protected static String formatJsonWithCustomBuilder(Object value, GsonBuilder builder) { return builder.create().toJson(value); } } 

My project directory listing is as follows and there is no build.xml as BUILD command is not successful.

The pom.xml maybe its missing any artifact(s)?
