To build a project with maven, you first need to download maven and install and configure it well.
Download address: http://maven.apache.org/download.html. Select the version you want to download and save it to the usual installation directory. Unzip maven to a common directory for software installation, such as: D:\Softwares\apache-maven-3.2.2.
Configure environment variables
Add a new system environment variable MAVEN_HOME and set its value to the destination of your installation MAVEN_HOME= D:\Softwares\apache-maven-3.2.2
Update the system PATH variable and add ;%MAVEN_HOME%\bin; to the end
At this point, the mavn environment is done. Test it. In the cmd command line window, you can check the version number of maven in mvn -v. Note that jdk needs to be installed before installing maven.
The above is the installation and configuration of maven, the next step is to use eclipse to create a maven project.
