Maven的第一个小程序
这里是介绍关于maven的第一个小程序
关于maven的安装 ： Install Maven in your computer
先看看目录结构：
这是本来的项目目录结构，由于maven有自己的目录结构，所以，下面的是加入maven元素后的目录结构：
即：
pom.xml文件要和src目录在同一级
在src目录下面，分别为main目录和test目录
在main目录下面存放项目中的模块类，如这里的com.b510.maven.hello.Hello.java
在test目录下面存放项目模块的测试类，如这里的com.b510.maven.hello.test.HelloTest.java
NOTE:
你所看到的有红色X标示错误提示，这是在Eclipse中的提示，这个可以不用理会。
接下来才是关键：
/maven_project/pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion> <groupId>com.b510.maven.hello</groupId>
<artifactId>hello-first</artifactId>
<version>SNAPSHOT-0.0.1</version> <dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
pom.xml文件，是project object manager的首字母缩写。即项目对象管理。
在pom.xml文件中，对于我们写的com.b510.maven.hello.Hello.java类，他的groupId = com.b510.maven.hello, artifactId = hello-first, version = SNAPSHOT-0.0.1
而我们的测试类，所依赖的包为junit，它属于test域。
下面是Hello类和HelloTest类
/maven_project/src/com/b510/maven/hello/Hello.java
/**
*
*/
package com.b510.maven.hello; /**
* @author Hongten
* @created 2014-7-5
*/
public class Hello { public static void main(String[] args) {
System.out.println("This is a test message!");
String str = new Hello().sayHello("Hongten", 20);
System.out.println(str);
} public String sayHello(String name, int age){
return "I'm " + name + ", I'm " + age + ", Hello";
}
}
/maven_project/src/com/b510/maven/hello/test/HelloTest.java
/**
*
*/
package com.b510.maven.hello.test; import static org.junit.Assert.*; import org.junit.Test; import com.b510.maven.hello.Hello; /**
* @author Hongten
* @created 2014-7-5
*/
public class HelloTest { @Test
public void testSayHello() {
Hello hello = new Hello();
assertEquals(hello.sayHello("Hongten", 20), "I'm Hongten, I'm 20, Hello");
} }
两个类都是很简单的类。
现在我们启动windows的控制台。即运行--> cmd，或Ctrl+R --> cmd
进入到项目的根目录：D:\Development\workspace\maven_project
1.运行命令：mvn compile
由于我们本地仓库中没有编译所需要的资源，所有，maven会到远程仓库中去获取资源到本地
下面是控制台运行效果：这里只是截取了部分log

我们看到maven执行了命令，并且从远程仓库下载了资源进行对项目进行编译，最后成功了。
这些远程资源会下载到我们电脑的：C:\Users\Administrator\.m2\repository 目录下面
然而，当我们的本地仓库中已经有了这些资源，在第二次执行上面的命令的时候，就不会到远程仓库中去获取资源，而是直接到本地仓库中获取。
下面是再次执行上面的命令：

执行命令后，我们再来看看项目的结构：
这时候，我们发现，项目中多了target目录，这是maven生成了目录。
请注意看：hello-first-SNAPSHOT-0.0.1.jar文件，这个是根据我们在pom.xml中配置的artifactId = hello-first, version = SNAPSHOT-0.0.1所生成的。
4.执行命令：mvn clean
即清除掉target目录即target目录下面的所有文件
D:\Development\workspace\maven_project>mvn clean

下面是运行后的效果：
这样做有什么用呢？
既然加载到了本地仓库，那么就类似于本地仓库中的junit模块一样，我们在使用junit的时候，只是在pom.xml文件中配置一下，并不需要引入junit的相关jar包，同理。
我们要使用/maven_project/src/com/b510/maven/hello/Hello.java类的时候，也不用引入该类的jar文件，只需要在pom.xml文件中配置即可。
如：
<dependencies>
<dependency>
<groupId>com.b510.maven.hello</groupId>
<artifactId>hello-first</artifactId>
<version>SNAPSHOT-0.0.1</version>
</dependency>
</dependencies>
第一个maven小程序，就差不多是这些，good luck！
