Maven 环境配置

1.安装maven

Installing Maven

1)Unpack the archive where you would like to store the binaries, eg:

Unix-basedoperating systems (Linux, Solaris and Mac OS X)

tarzxvf apache-maven-3.x.y.tar.gz

Windows

unzipapache-maven-3.x.y.zip

2)A directory called "apache-maven-3.x.y" will be created.

3)Add the bin directory to your PATH, eg:

Unix-basedoperating systems (Linux, Solaris and Mac OS X)

exportPATH=/usr/local/apache-maven-3.x.y/bin:$PATH

Windows

setPATH="c:\program files\apache-maven-3.x.y\bin";%PATH%

4)Make sure JAVA_HOME is set to the location of your JDK

5)Run "mvn --version" to verify that it is correctly installed.

大意翻译及操作：

Step1：下载，如下图

Step2: linux系统下：解压maven-3.5.3-bin.tar.gz文件到某个路径（如：/home/zm/JavaSoft/maven-3.5.3）

Windowns系统下：解压maven-3.5.3-bin.zip文件到某个路径

Step3：创建M2_HOME指向刚刚解压后的目录(环境配置)

linux系统:配置Maven环境：

sudo vim /etc/profile

export M2_HOME=/home/zm/JavaSoft/maven-3.5.3

export PATH=$PATH:$M2_HOME/bin

:wq

. /etc/profile

Windows配置Maven环境：系统-高级-环境变量【使用用户变量】

M2_HOME=D:\JavaSoft\maven3.5.3

PATH=%PATH%;%M2_HOME%\bin

Step4：查看maven是否安装好。

控制台执行mvn--v命令

The resultshould look similar to

Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T03:49:05+08:00)
Maven home: D:\java\maven\apache-maven-3.5.3\bin\..
Java version: 1.8.0_162, vendor: Oracle Corporation
Java home: D:\java\jdk\jdk1.8.0_162\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

自己Windows 10环境配置成功如下：

MAVEN_HOME=D:\Java\maven\apache-maven-3.5.3

path=%path%;%MAVEN_HOME%\bin

注意：maven要和JDK在同一个目录级别，查看maven是否配置成功

2.maven 仓库配置

1.首先配置下maven的库资源文件的存放路径：

1)$M2_HOME/conf/settings.xml:(/home/zm/JavaSoft/apache-maven-3.5.3/conf/settings.xml)配置本地仓库：<localRepository>(<localRepository>/home/zm/.m2/repository</localRepository>)

本地仓库配置过程中，插件和依赖包下载跟网络有关（可能Maven仓库:http://mvnrepository.com/在外网的原因）

2) 配置阿里的Maven仓库

执行maven命令

ArchetypeCatalog

This isa reference for the Archetype Catalog descriptor.

Theseare standard catalogfiles which containinformation about Archetypes so that users can be presented with a list ofarchetypes from any number of catalogs to generate new projects.

TheArchetype Plugin knows by default its internal catalog. It also knows about thelocal and remote catalogs:

local represents(描述) the ~/.m2/archetype-catalog.xmlcatalog file,

remote represents thehttp://repo.maven.apache.org/maven2/archetype-catalog.xml catalog file.

TheArchetype Plugin can also read catalogs from filesystem/HTTP by providing thepath/URL of a catalog file or of a directory containing an archetype-catalog.xml file.

<archetype-catalog xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-catalog/1.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-catalog/1.0.0http://maven.apache.org/xsd/archetype-catalog-1.0.0.xsd">

<archetypes>

</archetype>

</archetypes>

</archetype-catalog>

Maven阿里云配置

LINUX系统下阿里云配置：

$M2_HOME/conf/settings.xml:(/home/zm/JavaSoft/apache-maven-3.3.9/conf/settings.xml),进行如下配置：

Windows 系统下阿里云maven配置如下：(可以使用)

<mirror>

<id>alimaven</id>

<mirrorOf>central</mirrorOf>

<name>aliyunmaven</name>

<url>http://maven.aliyun.com/nexus/content/groups/public/</url>

</mirror>

Maven私服配置（一笔带过）

Nexus私服搭建

第一步：下载nexus-webapp-1.9.2.4.war包，然后拷贝到tomcat下的webapps目录中

第二步：启动tomcat 默认登录账户密码为: admin admin123

第三步：访问http://localhost:8080/项目名称/

Nexus仓库的默认的地址, nexus-2.1.2\WEB-INF\plexus.properties进行配置
