第一个手动maven工程--Hello

1.新建文件夹hello

2.建立maven的约定目录结构

3.在hello根目录建立src文件夹和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/maven-v4_0_0.xsd"> 
<modelVersion>4.0.0</modelVersion> 
<groupId>rjxy.maven</groupId>
 <artifactId>mavenDemo2</artifactId>
 <version>0.0.1-SNAPSHOT</version>  
 <name>Hello</name> 
 <dependencies> 
 <dependency>
<groupId>junit</groupId> 
 <artifactId>junit</artifactId> 
 <version>4.9</version> 
<scope>test</scope>
</dependency> 
 </dependencies> 
</project>

4.在D:\maven\hello\src\main\java\rjxy\maven下新建Hello.java

package rjxy.maven;
public class Hello{
public String sayHello(String name){
return "Hello "+name+"!";
}
}

5.在D:\maven\hello\src\test\java\rjxy\maven下建立He'llTest.java

 package rjxy.maven;  

 import org.junit.Test; 
 import static junit.framework.Assert.*;
 public class HelloTest {  
  @Test 
public void testHello(){  
 Hello hello = new Hello(); 
 String results = hello.sayHello("liuxin"); 
 assertEquals("Hello liuxin!",results); 
  } 
}

6.测试
