ubuntu apache-httpd java error-handling maven
I am using Java and Maven Project on Ubuntu but I am getting following error upon building Java code on NetBeans IDE: 
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:

The error is on following class package import:

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