Maven_001_HelloWorld

1.环境变量

添加：M2HOME:maven的安装目录(不是bin层)

修改：path中新加maven的安装目录,bin层

 

命令行中

mvn -v查看版本

 

2.pom.xml

在D:\Study\Maven\Demo\Maven_001_HelloWorld中建立

pom.xml

<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.artistninth.app</groupId>

  <artifactId>HelloWorld</artifactId>

  <version>1.0-SNAPSHOT</version>

  <packaging>jar</packaging>

 

   <dependencies>

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>4.8.2</version>

      <scope>test</scope>

    </dependency>

  </dependencies>

</project>

 

3.建立程序文件

在D:\Study\Maven\Demo\Maven_001_HelloWorld\src\main\java\com\artistninth\app中建立

SayHello.java

package com.artistninth.app;

 

public class SayHello{

public String say(String username){

return "Hello "+username;

}

}

 

4.建立测试文件(也可不要此步)

在D:\Study\Maven\Demo\Maven_001_HelloWorld\src\test\java\com\artistninth\app中建立

SayHelloTest.java

package com.artistninth.app;

import org.junit.*;

import static org.junit.Assert.*;

import com.artistninth.app.SayHello;

 

public class SayHelloTest{

 

@Test

public void myTest(){

SayHello sh = new SayHello();

String str = sh.say("ArtistNinth");

assertEquals(str,"Hello ArtistNinth");

}

}

 

 

4.编译

切换到D:\Study\Maven\Demo\Maven_001_HelloWorld，即pom.xml所在文件夹

mvn test 测试，可到D:\Study\Maven\Demo\Maven_001_HelloWorld\target\surefire-reports文件夹中查看详细信息

mvn compile编译

mvn package 打包

mvn clean 清空打包后的文件
