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仓库中有对应的jar包，所以要对依赖的项目运行mvninstall命令。

2
新建第二个项目模块HelloFriend文件夹及约定的文件夹结构

HelloFriend

--src

-----main

----------java

----------resources

-----test

---------java

---------resources

--pom.xml

3
在项目HelloFriend根文件夹建立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文件夹下新建文件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文件夹下新建測试文件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文件夹下运行命令mvn命令(注意到HelloFriend文件夹)

7
又一次在HelloFriend文件夹下运行命令mvnpackage
