Ubuntu 配置Maven

*非特别说明，默认root用户登录

1.下载maven

下载页面： https://maven.apache.org/download.cgi

$ wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.5.3/binaries/apache-maven-3.5.3-bin.zip  
$ unzip apache-maven-3.5.3-bin.zip 
$ sudo mv apache-maven-3.5.3 /opt/maven/

2.添加阿里云Maven仓库

编辑文件 settings.xml

<mirrors>
     <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>*</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>
</mirrors>

3.配置Maven环境变量

添加如下内容到文件/etc/profile和～/.bashrc中

export M2_HOME=/opt/tool/maven
export PATH=$PATH:$M2_HOME/bin

配置生效，执行如下命令：

source /etc/profile

4.检验配置结果

$ mvn -v
