You need to visit the Apache Maven downloads page and copy the link address of the binaries package. Next, use the wget command to download it on your server in the tmp directory:

wget https://dlcdn.apache.org/maven/maven-3/3.8.5/binaries/apache-maven-3.8.5-bin.tar.gz -P /tmp

At this point, you need to extract your downloaded file in the opt directory:

sudo tar xf /tmp/apache-maven-3.8.5-bin.tar.gz -C /opt
