## 下载 && 解压 ##

在官网：[http://maven.apache.org/download.cgi][http_maven.apache.org_download.cgi]  
下载 [https://mirrors.bfsu.edu.cn/apache/maven/maven-3/3.8.1/binaries/apache-maven-3.8.1-bin.zip][https_mirrors.bfsu.edu.cn_apache_maven_maven-3_3.8.1_binaries_apache-maven-3.8.1-bin.zip]

解压到指定目录(我是`~/javaweb/`) `unzip apache-maven-3.8.1-bin.zip -d ~/javaweb/`

查看该目录下的内容：

这熟悉的目录结构。

## 配置文件修改 ##

见 [Maven settings.xml 配置项  
][Maven settings.xml _]

## 环境变量配置 ##

只是为了在任意目录都可以直接使用`mvn`命令(且不需要输入命令的全路径)。  
本步骤可省略

配置项：

export MVN_HOME=/Users/leung/javaweb/apache-maven-3.8.1
    export PATH=$MVN_HOME/bin:$PATH

将其写入当前用户、当前shell的配置文件中，我的是`~/.zshrc`

写入后保存，重载配置文件，使之生效：`source ~/.zshrc`

查看配置是否生效：

leung@wuyujin ~ % echo $MVN_HOME
    /Users/leung/javaweb/apache-maven-3.8.1
    leung@wuyujin ~ % echo $PATH
    /Users/leung/javaweb/apache-maven-3.8.1/bin:/System/Volumes/Data/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home/:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin
    leung@wuyujin ~ % where mvn
    /Users/leung/javaweb/apache-maven-3.8.1/bin/mvn
    leung@wuyujin ~ % mvn --version
    Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)

## 使用测试 ##

其实可以在命令行直接使用maven命令新建不同类型的java项目。

新建一个web项目`mvn archetype:generate -DgroupId=com.wuyujin -DartifactId=webdemo -DarchetypeArtifactId=maven-archetype-webapp`

leung@wuyujin coderepo % mvn archetype:generate -DgroupId=com.wuyujin -DartifactId=webdemo -DarchetypeArtifactId=maven-archetype-webapp

接下来在命令行完成install和package, run jar.

cd webdemo
    mvn install
    mvn package

package 动作会生成一个 war  
该 wat 放置到 tomcat/jetty 等servlet容器中就可以运行/访问。

当执行过`mvn archetype:generate -DgroupId=com.wuyujin -DartifactId=webdemo -DarchetypeArtifactId=maven-archetype-webapp`之后，  
会生成`webdemo`，其中有`pom.xml`以及`src/`目录及`src/`目录下的默认源码。

mvn install 会生成 `target/`目录及其下内容。
