Maven快速入门

Maven的作用是来管理项目依赖构件（jar包）

1. 下载Maven
官方地址：http://maven.apache.org/download.cgi

2. 解压并新建一个本地库文件夹E:\MavenRepository

3.在settings.xml中配置本地仓库路径及国内镜像服务器地址

Maven国内镜像仓库：
http://maven.aliyun.com/nexus/content/groups/public

  <localRepository>E:\MavenRepository</localRepository>

  <mirrors>
<!--
    <mirror>
         <id>alimaven</id>
         <mirrorOf>central</mirrorOf>
         <name>aliyun maven</name>
         <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
     </mirror>
     <mirror>
         <id>jboss-public-repository-group</id>
         <mirrorOf>central</mirrorOf>
         <name>JBoss Public Repository Group</name>
         <url>http://repository.jboss.org/nexus/content/groups/public</url>
     </mirror>  
 -->
     <mirror>
      <id>alimaven</id>
      <mirrorOf>central</mirrorOf>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>
  </mirrors>

<profiles>
    <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>  
  </profiles>

若有代理请添加配置：

<proxies>
    <proxy>
         <id>my-proxy</id>
         <active>true</active>
         <protocol>http</protocol>
         <host>192.168.181.238</host>
         <port>8080</port>
      </proxy>
  </proxies>

4.配置maven环境变量

5.IDE配置

6.新建Maven项目

这里maven会自动下载需要的构件，完成后项目目录结构如下图

pom.xml报错原因是，因为创建的是JavaEE工程，需要添加web.xml，在工程上右键

将对应项目的文件可以拷贝到对应的maven项目目录下

7.配置pom.xml
