Introduction to Maven:
Maven is a project management tool that can automate the construction and dependency management of Java projects.
Maven can be seen as an accumulator of knowledge, originally created to simplify the build process in the Jakarta Turbine project. There are several projects, each with its own Ant build file, which are all slightly different. JARs are checked into CVS. We wanted a standard way to build projects, a clearly defined project composition, an easy way to publish project information, and a way to share JARs between multiple projects.
The result is a tool that can now be used to build and manage any Java-based project. We hope we've created something that makes the day-to-day work of Java developers easier and generally helps in understanding any Java-based project.

Method 1: Download the compressed package from the official website
Maven official website download
historical version download
Method 2: brew one-click installation
One-click installation of Maven and configuration of environment variables, the default installation is in/usr/local/Cellar/maven
brew install maven
Maven modifies the Ali source warehouse:
Modify: /maven/conf/settings.xml使用brew安装配置路径：/usr/local/Cellar/maven/3.8.3/libexec/conf
Copy the following configuration
<mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>
Maven modifies the local file storage path: (non-essential steps)
Find the <localRepository code block, which is commented by default
<localRepository>/user/local/maven/repository</localRepository>
Maven modifies environment variables (brew installation can be ignored)
1. Switch to the root directory first. If you are configuring environment variables for the first time, you need to create a .bash_profile file
cd ~
touch .bash_profile
2. Edit the .bash_profile file and add the following configuration
MAVEN_HOME is your Maven installation path
vi .bash_profile
export MAVEN_HOME=/usr/local/maven/apache-maven-3.6.3
export PATH=mavenhome/bin:PATH
3. Update the configuration file
source .bash_profile
4. Query the version number of maven
mvn -v
