In this tutorial, we will show you how to install Java JDK and Maven on Mac os.

Download and install files from the official website

1. Install Java JDK

1） Download the JDK installation package from the website

https://www.oracle.com/java/technologies/javase-downloads.html

JDK version, currently the most used JDK version is 8, so here I also choose jdk 1.8.

Then according to the operating system used, download the corresponding JDK, I am using mac, so I choose the max os version.

After the download is complete, install it.

2) Open the terminal, type java -version to check whether the installation is successful, if the version information is output, the installation is successful.

2. Install Maven

1) download maven

http://maven.apache.org/download.cgi

I chose Apache-Maven-3.6.3-bin.tar.gz

2) When the download is complete, double-click the file to unzip or use the tar command to unzip the file

3) Setting environment variables

Assuming the installation package path to         /Users/ylspirit/Downloads/apache maven -- 3.6.3

a. Enter vim ~/.bash_profile on the terminal
b. Enter i to start editing the file
c. Enter:
export M2_HOME =/Users/ylspirit/Downloads/apache maven -- 3.6.3
export PATH = $PATH: $M2_HOME/bin
d. Click ESC key and enter :wq to save the file and exit
e. Enter source ~/.bash_profile in the terminal to make the file effective

4) Type :mvn -v to check whether the installation is successful. If the version information is output, the installation is successful

➜  ~ mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

Install using brew package manager

1. Using brew install Java JDK 8

Use Homebrew to install, the version is the latest version of OpenJDK (Java 14):

➜  ~ brew install java

For the many use cases depending on an older version (commonly Java 8), the AdoptOpenJDK project makes it possible with an extra step.

➜  ~ brew tap adoptopenjdk/openjdk
➜  ~ brew cask install adoptopenjdk8

2. Using brew install Java Maven

Use Homebrew to install Maven, the latest version is: Maven 3.6.3

We run the following command to install:

➜  ~ brew install maven

If you want to install other versions of Maven, you can search through the brew search command first:

➜  ~ brew search maven
==> Formulae
maven ✔                maven-shell            [email protected]
maven-completion       [email protected]              [email protected]

Then install the required version, such as [email protected]:

➜  ~ brew install [email protected]
