Centos7部署maven

一、下载

[root@nacos ~]# wget https://mirrors.bfsu.edu.cn/apache/maven/maven-3/3.8.2/binaries/apache-maven-3.8.2-bin.tar.gz

二、部署

[root@nacos ~]# tar -xf apache-maven-3.8.2-bin.tar.gz -C /usr/local/

三、环境变量配置

# 在文件末尾增加以下配置
[root@nacos ~]# vim /etc/profile
export M2_HOME=/usr/local/apache-maven-3.8.2
export PATH=$PATH:$M2_HOME/bin

四、vim settings.xml

4.1、替换maven源，阿里云的源

[root@nacos ~]# cd /usr/local/apache-maven-3.8.2/conf/
[root@nacos conf]# vim settings.xml 
# 将(大概在159-166行)
    <mirror>
      <id>maven-default-http-blocker</id>
      <mirrorOf>external:http:*</mirrorOf>
      <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
      <url>http://0.0.0.0/</url>
      <blocked>true</blocked>
    </mirror>
# 替换成
 <mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>central</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
 </mirror>

4.2、指定下载资源位置

[root@nacos ~]# mkdir -p /usr/local/maven/repository

# 本地存储路径(大概53行)
[root@nacos conf]# vim settings.xml 
<localRepository>/usr/local/maven/repository</localRepository>

4.3、指定JDK版本

# 277行这样添加
<profile>
     <id>jdk-1.8</id>
     <activation>
       <activeByDefault>true</activeByDefault>
       <jdk>1.8</jdk>
     </activation>
       <properties>
         <maven.compiler.source>1.8</maven.compiler.source>
         <maven.compiler.target>1.8</maven.compiler.target>
         <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
       </properties>
</profile>

五、验证

[root@nacos ~]# mvn -version
