Maven: 用来管理项目依赖,构件
maven中央库：http://repo1.maven.org/maven2/
maven国内镜像：http://maven.aliyun.com/nexus/content/groups/public
maven本地库：
查询maven依赖(http://mvnrepository.com/)
在maven库中，每个maven构建由Group Id, Artifact Id, Version唯一标识。
Maven环境搭建
1． 下载apache-maven-3.5.0-bin.zip
2． 修改conf目录下的setting.xml
//设置maven本地库
~~~
<localRepository>d:/.m2/repository</localRepository>
<!--设置maven镜像（从哪下载）-->
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror>
~~~
3. 在eclipse中配置maven
4. 创建maven工程(create a simple project(skip archetype selection))
填写Group Id, Artifact Id, Version
注意：第一个使用maven创建工程会比较慢，因为需要联网下载创建maven工程所必须的构建。
工程类型为war的工程需要web.xml(工程右键：JAVAEE Tools->Generate Deployement Descriptor Stub)
5. 编写POM文件（depencies & build）
~~~

注意：第一次maven build会比较慢，因为需要联网下载所有依赖。
若想使用jdk1.8, tomcat8, 请参考https://blog.csdn.net/wild46cat/article/details/52412330
运行maven工程（2种方式）
1. 原来的方式，设置jdk, 部署tomcat
2. Maven命令方式：
工程右键-》run as maven build -> tomcat7:run
