maven安装部署

1.安装

1.1.主机环境

• OS：CentOS7
• Jdk：1.8
• Maven：3.6

1.2.下载

• 下载二进制包，，可以去官方下载或者阿里云镜像(推荐)
• 官网：https://maven.apache.org/download.cgi
• 阿里云镜像：https://mirrors.aliyun.com/apache/maven/maven-3/

1.3.解压

• 下载后解压，推荐解压到/opt目录
• tar -xf apache-maven-3.6.3-bin.tar.gz -C /opt

1.4.添加环境变量

• 在/etc/profile底部追加下述内容

export MAVEN_HOME=/opt/apache-maven-3.6.3
export PATH=$PATH:$MAVEN_HOME/bin

1.5.验证

• mvn -v

# mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/apache-maven-3.6.3
Java version: 1.8.0_311, vendor: Oracle Corporation, runtime: /usr/java/jdk1.8.0_311-amd64/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-1160.el7.x86_64", arch: "amd64", family: "unix"

2.配置Maven

2.1.配置本地仓库目录

• 默认在：${user.home}/.m2/repository, 建议修改一下

vim conf/settings.xml

<localRepository>/opt/apache-maven-3.6.3/repository</localRepository>

2.2.配置国内镜像地址

• 国外源较慢，因此配置为国内镜像源

  <mirrors>
      <mirror>
            <id>alimaven</id>
            <name>aliyun maven</name>
             <url>https://maven.aliyun.com/nexus/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
      </mirror>
  </mirrors>

2.3.验证

• mvn help:system: 该命令会首次下载很对依赖，并输出一些环境变量之类的信息
• 如无报错，则Maven安装配置完成
