3.将maven项目jar纳入maven仓库，Mave项目依赖另外一个Maven项目的案例



1
若想让maven项目依赖另外一个maven项目，被依赖的项目要在maven仓库中有相应的jar包，所以要对依赖的项目执行mvninstall命令。

2
新建第二个项目模块HelloFriend目录及约定的目录结构

HelloFriend

 --src

 -----main

 ----------java

 ----------resources

 -----test

 ---------java

 ---------resources

 --pom.xml

3
在项目HelloFriend根目录建立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>cn.toto.maven</groupId>

 
<artifactId>HelloFriend</artifactId>

 
<version>0.0.1-SNAPSHOT</version>

 
<name>HelloFriend</name>

        
<dependencies>

                  
<dependency>

                           
<groupId>junit</groupId>

                           
<artifactId>junit</artifactId>

                           
<version>4.9</version>

                           
<scope>test</scope>

                  
</dependency>                 

                  
<dependency>

                           
<groupId>cn.toto.maven</groupId>

                           
<artifactId>Hello</artifactId>

                           
<version>0.0.1-SNAPSHOT</version>

                           
<scope>compile</scope>

                  
</dependency>                 

        
</dependencies>

</project>

4
在src/main/java/cn/toto/maven目录下新建文件HelloFriend.java文件

package cn.toto.maven;

import cn.toto.maven.Hello;

public class HelloFriend {

        
public String sayHelloToFriend(String name){

                  
Hello hello = new Hello();

                  
String str = hello.sayHello(name)+" I am "+this.getMyName();

                  
System.out.println(str);

                  
return str;

        
}

        
public String getMyName(){

                  
return "John";

        
}

}

5
在/src/test/java/cn/toto/maven目录下新建测试文件HelloFriendTest.java

package cn.toto.maven;

import static junit.framework.Assert.assertEquals;

import org.junit.Test;

import cn.toto.maven.Hello;

public class HelloFriendTest {

        
@Test

        
public void tesHelloFriend(){

                  
HelloFriend helloFriend = new HelloFriend();

                  
String results = helloFriend.sayHelloToFriend("tuzuoquan");

                  
assertEquals("Hello tuzuoquan! I am John",results);             

        
}

}

6
在HelloFriend目录下执行命令mvn命令(注意到HelloFriend文件夹)

7
重新在HelloFriend目录下执行命令mvnpackage
