maven 安装配置maven

maven 首先要在linux命令行就能使用maven进行构建，jenkins调用linux本地maven插件，工具，对我们项目进行构建

maven安装在linux ci-node2 服务器上

Centos 下安装 Maven

maven是java写的，所以需要安装jdk

安装 JDK

可以使用 YUM 方式安装安装 open JDK1.8 版本，也可以使用我提供的 rpm 安装，我们使用 RPM 方式安装

 rpm -ivh jdk-8u121-linux-x64.rpm

[root@ci-node2 src]# java -version 
java version "1.8.0_121" 
Java(TM) SE Runtime Environment (build 1.8.0_121-b13) 
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

改名

[root@ci-node2 local]# mv apache-maven-3.3.9/ maven

配置 Maven

编辑 /etc/profile 文件，在末尾添加 export PATH=/usr/local/maven/bin/:$PATH ，将 maven 命令加入系统环境变量。

就可以直接执行mvn命令

vim 保存wq 然后source /etc/profile

[root@ci-node2 local]# source /etc/profile

可以了 maven配置完成

[root@ci-node2 local]# mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/maven
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: /usr/java/jdk1.8.0_121/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"

这样maven就安装成功，验证maven是否安装成功

这个命令能执行成功，代表maven安装完成了
