11.2. Maven environment configuration

Maven is a Java-based tool, so the first thing to do is to install JDK.

If you have not installed JDK, you can refer to our Java 开发环境配置 .

11.2.1. System requirements ¶

Project	Request
JDK	Maven 3.3 requires JDK 1.7 or above
	Maven 3.2 requires JDK 1.6 or above
	JDK 1.5 or above is required for Maven 3.0
Memory	There is no minimum requirement
Magnetic disk	The installation of Maven itself requires approximately 10 MB space. In addition, the extra disk space will be used for your local Maven repository. The size of your local warehouse depends on usage, but expect at least 500 MB
Operating system	There is no minimum requirement

11.2.2. Check Java installation ¶

Operating system	Task	Command
Windows	Open the command console	c:\> java -version
Linux	Open the command terminal	# java -version
Mac	Open the terminal	$ java -version

11.2.3. Maven download ¶

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

Download the corresponding packages on different platforms:

System	Package name
Windows	Apache-maven-3.3.9-bin.zip
Linux	Apache-maven-3.3.9-bin.tar.gz
Mac	Apache-maven-3.3.9-bin.tar.gz

After downloading the package, extract it to the corresponding directory:

System	Storage location (can be configured according to your own situation)
Windows	E:Mavenapache-maven-3.3.9
Linux	/ usr/local/apache-maven-3.3.9
Mac	/ usr/local/apache-maven-3.3.9

11.2.4. Set the Maven environment variable ¶

Add the environment variable MAVEN_HOME:

System	Configuration
Windows	Right-click “computer”, select “Properties”, then click “Advanced system Settings” and click “Environment variables” to set environment variables. The following system variables need to be configured: New system variabl `MAVEN_HOME` , variable value: `E:\ Maven\ apache-maven- 3.3.9` Edit system variabl `Path` , add the variable value: `;% MAVEN_HOME%\ bin` 注意 Note that multiple values need to be separated by semicolons, and then click OK.
Linux	Download and decompress: # wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz # tar -xvf apache-maven-3.3.9-bin.tar.gz # sudo mv -f apache-maven-3.3.9 /usr/local/ Editing `/etc/profile` File `sudo vim /etc/profile` To add the following code at the end of the file export MAVEN_HOME=/usr/local/apache-maven-3.3.9 export PATH=${PATH}:${MAVEN_HOME}/bin Save the file and run the following command to make the environment variable take effect: # source /etc/profile Enter the following command in the console. If you can see the relevant version information of Maven, it means that Maven has been installed successfully: # mvn -v
Mac	Download and decompress: $ curl -O http://mirrors.hust.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz $ tar -xvf apache-maven-3.3.9-bin.tar.gz $ sudo mv -f apache-maven-3.3.9 /usr/local/ Editing `/etc/profile` File `sudo vim /etc/profile` To add the following code at the end of the file export MAVEN_HOME=/usr/local/apache-maven-3.3.9 export PATH=${PATH}:${MAVEN_HOME}/bin Save the file and run the following command to make the environment variable take effect: $ source /etc/profile Enter the following command in the console. If you can see the relevant version information of Maven, it means that Maven has been installed successfully: $ mvn -v Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00) Maven home: /usr/local/apache-maven-3.3.9 Java version: 1.8.0_31, vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/jre Default locale: zh_CN, platform encoding: ISO8859-1 OS name: "mac os x", version: "10.13.4", arch: "x86_64", family: "mac"

# tar -xvf  apache-maven-3.3.9-bin.tar.gz
# sudo mv -f apache-maven-3.3.9 /usr/local/

Editing /etc/profile File sudo vim /etc/profile To add the following code at the end of the file

export MAVEN_HOME=/usr/local/apache-maven-3.3.9
export PATH=${PATH}:${MAVEN_HOME}/bin

Save the file and run the following command to make the environment variable take effect:

# source /etc/profile

Enter the following command in the console. If you can see the relevant version information of Maven, it means that Maven has been installed successfully:

# mvn -v
