To manage projects done in Java, there is no better tool than Apache Maven. This fantastic tool, belonging to the Apache foundation, comes with predefined objectives to perform certain clearly defined tasks, such as code compilation and packaging.

Many features make Maven a great tool. However, the key is that Maven is ready for network use. Also, its functions are made extensible by the ability to install plugins. Finally, Maven relies on the Project Object Model (POM) to describe the project, as well as its dependencies for later deployment.

Installing Apache Maven on Ubuntu 20.04

Before starting the installation of Apache Maven, it is advisable to perform a complete update to the operating system.

So, open a terminal or connect via SSH to your server:

:~$ sudo apt update
:~$ sudo apt upgrade

Once all the packages have been installed without problems, we can start.

1.- Install Java on Ubuntu 20.04

Apache Maven is created in Java, so the operating system where it is going to be installed has to have Java. This, in Ubuntu 20.04 is not a problem.

This will install Java version 11, which is LTS, and already comes in the official repositories of the distribution.

If you want to install Java version 14, you can do it through this tutorial.

Now, verify that Java has been installed correctly, executing the Java command, for example, to know the version installed:

:~$ java --version
openjdk 11.0.7 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mixed mode, sharing)

This indicates that Java has been installed and is working properly.

2.- Download, install and test Apache Maven on Ubuntu 20.04

Now we can download Apache Maven from one of the Apache mirrors. We do this intending to get the latest stable version and thus take better advantage of the features offered.

So, go to the /tmp directory from there with the help of the wget command and download.

:~$ cd /tmp/
:~$ wget -c http://mirrors.advancedhosters.com/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
--2020-05-14 05:15:57-- http://mirrors.advancedhosters.com/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

At the moment, the last stable version of Apache Maven is 3.6.3

Then, decompress the file and move it to /opt/

:~$ tar -zxvf apache-maven-3.6.3-bin.tar.gz
:~$ sudo mv apache-maven-3.6.3 /opt/maven

And to make Apache Maven available from anywhere on the prompt, a new file has to be created within the bash profile.

:~$ sudo nano /etc/profile.d/maven.sh

And add the following:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export M2_HOME=/opt/maven
export PATH=${M2_HOME}/bin:${PATH}

Save the changes and close the file.

Apply the changes by running this command:

:~$ source /etc/profile.d/maven.sh

Finally, to test Apache Maven, just show the installed version.

:~$ mvn -version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/maven
Java version: 11.0.7, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.4.0-26-generic", arch: "amd64", family: "unix"

So, enjoy it because it is properly installed.

Conclusion

Apache Maven is a very important tool in the development of projects, especially if they are Java. Its installation is not difficult but its benefits are many.

The post How to install Apache Maven on Ubuntu 20.04? appeared first on Linux Windows and android Tutorials.

Prerequisite

To be able to run Maven it is imperative to have Java JDK configured. To see how to download and install it, please check our post about Tomcat in Windows 10/Server.

Download Maven.

The first thing you have to do is download the latest version of Apache Maven. With this in mind, go to your page and select the binary files in ZIP format. At the time of writing this article, the version is 3.6.2

Once downloaded the file, unzip it in the location you want. However, I recommend you to do it at the root of the C unit.

Creates environment variables.

Once the folder has been downloaded and unzipped, all that remains is to add environment variables. Please remember that Maven runs through the CMD. In that case, it is necessary to add the environment variable to run the program from any Command Prompt. Otherwise, we would have to go to the location where the program is decompressed every time you want to run it. If you want to know how to do it please check our post about Wget in Windows 10. First, add a name variable MD_HOME and use as the value of the variable the location where you unzipped the binary.

Then edit the Path variable and add a new value with the following address: C:\apache-maven-3.6.2\bin

Testing Maven.

Now all that remains is to prove that everything is in order and Maven runs successfully. With this intention open a CMD and type the following command:

mvn-v

If running the command gives a result like the previous one, then the installation was successful, and we are now ready to use this tool. Very well we have seen how to install Maven in Windows 10/Server. From now on you can take advantage of all the advantages it offers. For example to manage and build Java projects. This is all for the moment, see you soon.

Finally, Maven relies on the Project Object Model (POM) to describe the project, as well as its dependencies for later deployment.

If you want to learn how to install Apache Maven on Ubuntu 18.04 or Debian 9, you can read our tutorial:

How to install Apache Maven on Ubuntu 18.04 / Debian 9?

So, let’s start to install Apache Maven.

Installing Apache Maven on Debian 10

Before starting it is advisable to make an update to the whole system. To do this, open a terminal session and run the following:

:~$ sudo apt update && sudo apt upgrade

In case your Debian system does not have sudo active, you can learn how to activate it with the following post:

How to enable sudo in Debian 10?

Now with the updated system you will have at your disposal the last patches to be guaranteed and thus you will have a more stable system.

Install Java on Debian 10

Apache Mave is built in JAva, so it requires it to be installed on the system. You can choose between the proprietary version of Oracle or OpenJDK that comes in the Debian repositories. We will use this last option.

:~$ sudo apt install openjdk-11-jre openjdk-11-jdk

After finishing the installation, we check that everything is OK showing the installed version of Java.

:~$ java --version

So, everything’s right for now.

Install Maven. Method 1: Using the official repositories

Apache Maven is included in the official Debian 10 Buster repositories. However, this version is not the latest available. Then, we will not be able to get the latest application updates.

So to install it, on the terminal, run the following:

:~$ sudo apt install maven

That is it. It is the easiest method but we will always be outdated and it is not convenient. So I will show you a way to install the latest version available.

Method 2: Download it and install it

The second method is a little more complicated but not so much. In this method, we will download the binary from the Apache servers and install it normally.

This method ensures that you always download the latest version available at any time. So let’s go for it.

Navigate to the tmp folder and download alli Apache Maven.

:~$ cd /tmp/
:~$ wget -c https://www-us.apache.org/dist/maven/maven-3/3.6.2/binaries/apache-maven-3.6.2-bin.tar.gz

Then unzip the file and move it to /opt/.

:~$ tar -zxvf apache-maven-3.6.2-bin.tar.gz
:~$ sudo mv apache-maven-3.6.2 /opt/maven

Apache Maven works with Java environment paths and variables. Then you have to define them before using it. To do this, create a file called maven.sh in /etc/profile.d/ and add the following:

:~$ sudo nano /etc/profile.d/maven.sh

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export M2_HOME=/opt/maven
export PATH=${M2_HOME}/bin:${PATH}

To apply the changes, just use the following command:

:~$ source /etc/profile.d/maven.sh

Finally, you will be able to show the installed version of Maven.

:~$ mvn -version

This indicates that Maven is ready for work.

Conclusion

Apache Maven is a fantastic tool for Java projects. These projects that every day continue to be references in many companies. So learning how to install Apache Maven on Debian 10 could be quite useful.

Apache Maven

Maven is an open source tool that allows you to manage projects made in Java. It belongs to the Apache Foundation, which gives us a guarantee of quality and stability. One of the main achievements of Maven is the unification of criteria at the time of verifying the .JAR files generated. Moreover, it is possible to share JARs across several projects.

So, some of the Maven’s goals are as follows:

• Making the build process easy.
• Providing a uniform build system, quality project information, and guidelines for best practices development.
• Allowing transparent migration to new features.

So, let us start to install Apache Maven.

1. Update the system

The first step is to have the system updated. That is to say that all the packages of the system are to their last version.

:~$ su
:~# yum update

This way, you will have a more stable system thanks to the security patches installed. It is also advisable to improve the robustness of some programs that could generate a security problem.

2.- Install Java on CentOS 7

Maven requires Java to work. Although it also requires the latest version of it, so we will be able to use the OpenJDK that comes in CentOS 7 refuels.

For that, in a terminal, run the following:

:~# yum install java-1.8.0-openjdk-devel

To be sure everything went well, you can check the Java version.

:~# java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-b04)
OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)

Now it is necessary to define the JAVA_HOME variable in our system.

:~# echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")" | tee -a /etc/profile
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/
:~# source /etc/profile

Now we can install Apache Maven.

3.- Install Apache Maven on CentOS 7

To do this, let’s download it from the project repositories. At the time of writing this post, the current version is 3.6.1.

:~# cd /tmp/
:~# wget http://www-us.apache.org/dist/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

After that, decompress it.

:~# tar -zxvf apache-maven-3.6.1-bin.tar.gz

Then, move it to the /opt/ directory and change the owner.

:~# mv apache-maven-3.6.1 /opt/
:~# chown -R root:root /opt/apache-maven-3.6.1/

After this, it is recommended to make a symbolic link to the Maven directory. This is to avoid problems with the Maven version.

:~# ln -s /opt/apache-maven-3.6.1 /opt/apache-maven

And add it to the environment variable.

:~# echo 'export PATH=$PATH:/opt/apache-maven/bin' | tee -a /etc/profile
export PATH=$PATH:/opt/apache-maven/bin
:~# source /etc/profile

Then, we can verify Maven’s version.

:~# mvn --version
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-04T15:00:29-04:00)
Maven home: /opt/apache-maven
Java version: 1.8.0_212, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.12.1.el7.x86_64", arch: "amd64", family: "unix"

So, Apache Maven is correctly installed.

Conclusion

Installing Maven on CentOS 7 is not difficult however, it is a tool widely used by Java developers. So, because of its great project management capabilities, Apache Maven has earned its place of honor in Java programming.

So, please share this post.

To manage projects done in Java, there is no better tool than Apache Maven. This fantastic tool, belonging to the Apache foundation, comes with predefined objectives to perform certain clearly defined tasks, such as code compilation and packaging.

There are many features that make Maven a great tool. However, the key is that Maven is ready for network use. In addition, its functions are made extensible by the ability to install plugins. Finally, Maven relies on the Project Object Model (POM) to describe the project, as well as its dependencies for later deployment.

So, let’s start to install Apache Maven.

1. Upgrade the system

First of all, I recommend you to update the system. You should always do this frequently. So open a terminal and run.

:~$ sudo apt update && sudo apt upgrade

Note: Your user must be able to use sudo.

Now you’ll have a more stable and secure system.

2. Install Oracle Java

Apache Maven requires Java for its operation. It does so because it is made with this programming language, so you will have to install it. However, don’t worry because here I show you how to do it in an easy and simple way.

Once you have finished installing Java, you will be able to continue.

3. Install Apache Maven

First option: Installing Maven using APT

There are two ways to install Apache Maven. The first and simplest is to do it through the main repositories of Ubuntu and Debian, that is, just enough:

:~$ sudo apt install maven

And that’s it.

This method is the simplest, but it has the main problem, the latest version of Maven is not installed. This is because repositories freeze versions of programs for stability.

Second Option: From the source code

In this process, we’ll do a few more steps, but we’ll always have the latest version available. If you work with Java you will know that there are always new features in each release and thus be able to take better advantage of its potential.

So, let’s do it. Just run:

:~$ wget -c https://www-us.apache.org/dist/maven/maven-3/3.6.0/binaries/apache-maven-3.6.0-bin.tar.gz

Note: At the time of writing this post, the latest stable version is 3.6.0.

Then, decompress it.

:~$ tar -zxvf apache-maven-3.6.0-bin.tar.gz

Now, move the folder to /opt.

:~$ sudo mv apache-maven-3.6.0 /opt/maven

It is now necessary to set the environment variables. Create a file called maven.sh in /etc/profile.

:~$ sudo nano /etc/profile.d/maven.sh

And add the following lines.

export JAVA_HOME=/usr/lib/jvm/java-11-oracle
export M2_HOME=/opt/maven
export PATH=${M2_HOME}/bin:${PATH}

Note: The JAVA_HOME variable can be obtained with the command update-java-alternatives -l.

Finally, run:

:~$ source /etc/profile.d/maven.sh

Finally, check the Maven version.

:~$ mvn -version

And that’s it.

Conclusion

Apache Maven is a very important tool in the development of projects, especially if they are Java. Its installation is not difficult but its benefits are many.
