什么是Maven
1 依赖的管理：仅仅通过jar包的几个属性，就能确定唯一的jar包，在指定的文件pom.xml中，只要写入这些依赖属性，就会自动下载并管理jar包。
2 项目的构建：内置很多的插件与生命周期，支持多种任务，比如校验、编译、测试、打包、部署、发布...
3 项目的知识管理：管理项目相关的其他内容，比如开发者信息，版本等等
Maven库：http://repo2.maven.org/maven2/
中央仓库资源：http://mvnrepository.com/
下载安装
去maven的官网上下载，http://maven.apache.org/download.cgi，根据自己电脑的实际情况选择对应的文件。
下载完毕后将其解压到任意位置，例如我的电脑上就是D:mavenapache-maven-3.2.5
Maven环境配置
注意：安装maven之前，必须先确保你的机器中已经安装了JDK，如果是Maven3则必须JDK1.7以上。
1．解压压缩包
2．添加环境变量MAVEN_HOME，值为apache-maven的安装路径：D:mavenapache-maven-3.2.5
3．在Path环境变量的变量值末尾添加%MAVEN_HOME%in;
4．在cmd输入mvn –version，如果出现maven的版本信息，说明配置成功。
本地仓储配置
如果您不配置，默认会在如下位置存放从远程下载到的包：
从中央仓库下载的jar包，都会统一存放到本地仓库中。我们需要配置本地仓库的位置。
打开maven安装目录，打开conf目录下的setting.xml文件。
可以参照下图配置本地仓储位置。
修改默认中央仓库地址：D:MavenResponse
Ecplise使用Maven
1.插件安装
依次选择Eclipse菜单栏的“Help”菜单à“Instance NewSoftWare”菜单项，就会弹出如下对话窗口：
，然后点击add按钮，会出现一个对话框，这个对话框就是用于添加一个插件地址的。在“Name”对应的输入框里输入该操作的一个标识名。在“Location”对应的输入框里输入这个插件的安装地址。注：Maven的Eclipse插件地址为：http://download.eclipse.org/technology/m2e/releases。输入后，如下图所示：
2.Ecplise配置maven
Maven常用的命令
以下所有的命令都要在项目的根目录下进行。
Maven提供了一套命令，我们可以在dos小黑窗中使用，当对Maven项目使用这些命令的时候我们应该切换到该项目的根目录下。
命令一：
mvn clean
这个命令可以清除我们的target文件夹（这个文件夹存放编译后的.class文件）
命令二：
mvn compile
和上面的命令相反，这个命令是编译一个项目的，前提是我们当前命令行位置为该项目的根目录下。
命令三：
mvn test
这个命令可以进行单元测试，测试test文件夹下的方法（test文件夹下的java文件格式名为：XxxTest.java）
命令四：
mvn package
将项目打包，如果是java项目就打包为.jar文件，如果是web项目及打包成.war文件。
命令五：
mvn install
将一个项目打包放在本地仓库中，以便多个项目使用。
创建Maven项目容易出现的问题
Maven的常规使用
1.设置全局的jdk，在setting.xml文件中的profiles元素下添加如下profile元素：
<profile> <id>jdk17</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>
2.设置局部的jdk，在项目的pom,xml文件中添加如下build元素：
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build>
3.添加依赖
我们在Maven项目中创建一个Servlet，我们需要导入servlet-api.jar,只要在pom.xml 的dependencies视图下进行add就好了。
4.依赖范围
在我们设置依赖的时候，会有一项Scope，里面有：
compile，provided，runtime，test，system五项。
（图片来自网络）
Maven默认的是compile，即对于编译classpath，测试classpath，运行时classpath 都需要这个jar包。
尤其值得注意的是provided，这个就像servlet-api那样，我们编译测试都需要这个jar包，但是当上传到服务器的时候就不再需要了（Tomcat的lib下有），如果这里我们默认compile，那么当程序在服务器上运行的时候将出现jar包的冲突！
5.Maven工程的多模块项目、项目与项目之间的引用

7.maven的两种可运行jar打包方式。
1、内置依赖，
<plugins> <!-- 内置打包法 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <!-- 用这个maven打包插件 --> <artifactId>maven-shade-plugin</artifactId> <version>2.3</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <!-- 默认值为true.注意这个属性,如果你用这个插件来deploy,或者发布到中央仓库，这个属性会缩减你的pom文件,会把你依赖的<dependency>干掉 --> <createDependencyReducedPom>false</createDependencyReducedPom> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.handlers</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.schemas</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <!-- 这个是你的程序入口文件 --> <mainClass>com.alibaba.dubbo.container.Main</mainClass> </transformer> </transformers> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.4</version> <configuration> <!-- 设置字符编码集 --> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins>
2、外部依赖。
<plugins> <!-- 打包jar文件时，配置manifest文件，加入lib包的jar依赖 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <classesDirectory>target/classes/</classesDirectory> <archive> <manifest> <mainClass>com.alibaba.dubbo.container.Main</mainClass> <!-- 打包时 MANIFEST.MF文件不记录的时间戳版本 --> <useUniqueVersions>false</useUniqueVersions> <addClasspath>true</addClasspath> <classpathPrefix>lib/</classpathPrefix> </manifest> <manifestEntries> <Class-Path>.</Class-Path> </manifestEntries> </archive> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <type>jar</type> <includeTypes>jar</includeTypes> <useUniqueVersions>false</useUniqueVersions> <outputDirectory> ${project.build.directory}/lib </outputDirectory> </configuration> </execution> </executions> </plugin> </plugins>
8.maven上传源码到私服
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <version>3.0.1</version> <configuration> <attach>true</attach> </configuration> <executions> <execution> <phase>compile</phase> <goals> <goal>jar</goal> </goals> </execution> </executions> </plugin>
