Maven基础介绍
今天索性研究了下maven 一切从零开始，我将讲解Maven
?
Maven 构建工具，很强大，也很成功的开源软件
?
Maven Getting Start
?
1.下载Maven
官网 :?http://maven.apache.org/
?
现在版本为： Maven 3.0.4
?
下载地址：
?
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>my-app</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies></project>?
?
mvn eclipse:eclipse?
?
生成Eclipse 工程
?
project?? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?为根目录
modelVersion?为Maven Module的Version
groupId??为公司和组的名字
artifactId?jar或者source目录
packaging?形式（jar or war or ear?）
version?jar version
name?project name
url?链接网络site
description?描述说明
?
常用Maven 命令：
?
mvn clean
mvn eclipse:eclipse
mvn compile
mvn test
mvn test-compile
mvn?package
mvn install
mvn clean
mvn site
?
?
1.什么是Maven的本地目录
?
? 默认情况下为：Windows ?C:\Documents and Settings\username\.m2
? 想想.m2一看就不像目录，所以我们要改目录：
?1.1配置默认的本地目录，修改maven配置文件
? ? ?{M2_HOME}\conf\setting.xml
?
?
<settings> <!-- localRepository | The path to the local repository maven will use to store artifacts. | | Default: ~/.m2/repository <localRepository>/path/to/local/repo</localRepository> --> <localRepository>D:/maven_repo</localRepository>?
?
2.Maven的中心库
如果本地没有jar包的话，Maven就会默认的从http://repo1.maven.org/maven2/.下载相应的jar包，这个地址就是Maven的中心库
?
3.安装本地jar包
?
1.
?
mvn install:install-file -Dfile=c:\kaptcha-2.3.jar -DgroupId=com.google.code -DartifactId=kaptcha -Dversion=2.3 -Dpackaging=jar
?
?2.
