How to install Maven

A Maven install is one of the easier software installations you can do. At a high level, the steps to install Maven are:

  1. Download Maven binaries from the Apache website.
  2. Unzip the Apache Maven download, and move the folder to a place on your computer where you keep all of your other DevOps tools.
  3. Add system variables named MAVEN_HOME and M2_HOME, and point both of these variables to the root Maven directory. The root Maven directory will contain a folder named \bin, which contains the pivotally important mvn command-line utility.
  4. The root Maven directory contains a subfolder named \bin. Add this \bin directory to the OS' path. This makes the mvn command-line tool universally available to the OS.

In my personal development environments, I like to rename the Maven directory _maven, and when I install Maven on a Windows machine, I place that folder directly in the root of the C: drive. Here's how the system variables and edited path look after you successfully configure and install Maven.


Install Nexus OSS




tar -xzf latest-unix.tar.gz


./nexus start

Add hole in firewall for port 8081

sudo firewall-cmd --permanent --add-port=8081/tcp

sudo firewall-cmd --reload



The default username and password for the Nexus Maven repository is: admin:admin123. When the Nexus repository manager’s administrative console loads, log in with these credentials.

Maven Installation

System Requirements


Java Development Kit (JDK) Maven 3.3+ require JDK 1.7 or above to execute - they still allow you to build against 1.3 and other JDK versions by Using Toolchains
Memory No minimum requirement
Disk Approximately 10MB is required for the Maven installation itself. In addition to that, additional disk space will be used for your local Maven repository. The size of your local repository will vary depending on usage but expect at least 500MB.
Operating System No minimum requirement. Start up scripts are included as shell scripts and Windows batch files.


Maven is distributed in several formats for your convenience. Simply pick a ready-made binary distribution archive and follow the installation instructions. Use a source archive if you intend to build Maven yourself.

In order to guard against corrupted downloads/installations, it is highly recommended to verify the signature of the release bundles against the public KEYS used by the Apache Maven developers.

  Link Checksums Signature
Binary tar.gz archive apache-maven-3.6.0-bin.tar.gz apache-maven-3.6.0-bin.tar.gz.sha512 apache-maven-3.6.0-bin.tar.gz.asc
Binary zip archive
Source tar.gz archive apache-maven-3.6.0-src.tar.gz apache-maven-3.6.0-src.tar.gz.sha512 apache-maven-3.6.0-src.tar.gz.asc
Source zip archive

Previous Releases

It is strongly recommended to use the latest release version of Apache Maven to take advantage of newest features and bug fixes.

If you still want to use an old version you can find more information in the Maven Releases History and can download files from the archives for versions 3.0.4+ and legacy archives for earlier releases.
