linux（centos 7）安装 maven

maven需要JDK的支持，所以如果未安装JDK的请先安装JDK

下载对应版本&安装

# 下载maven包命令，当前在哪个目录下载到哪个目录
wget https://dlcdn.apache.org/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

解压

# 在Maven压缩包当前目录下解压
tar -xvf apache-maven-3.6.3-bin.tar.gz

配置环境变量

 vim /etc/profile

添加如下：

#maven
export MAVEN_HOME=/home/xxx/bonc/download/apache-maven-3.6.3
export PATH=$PATH:$MAVEN_HOME/bin

使配置文件生效

source /etc/profile

验证是否安装成功

# 使用查看maven版本命令查看maven安装情况，如正确出现maven版本则表示安装成功
[root@localhost ~]# mvn -version

配置阿里云仓库

maven默认国外仓库，在拉取jar包的时候速度会非常慢，所以配置阿里云仓库，让拉取jar速度提升

[root@localhost ~]# vim /home/xxx/bonc/download/apache-maven-3.6.3/conf/settings.xml 
  
    
        alimaven
        aliyun maven
        http://maven.aliyun.com/nexus/content/groups/public/
        central
    
    
         repo2
         Mirror from Maven Repo2
         https://repo.spring.io/plugins-release/
         central
   

配置本地依赖下载位置

[root@localhost ~]# vim /home/xxx/bonc/download/apache-maven-3.6.3/conf/settings.xml 
/home/xxx/bonc/download/apache-maven-3.6.3/localRepository
