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

  4.0.0

  cn.toto.maven

  HelloFriend

  0.0.1-SNAPSHOT

  HelloFriend

 

        

                  

                            junit

                            junit

                            4.9

                            test

                                    

                  

                  

                            cn.toto.maven

                            Hello

                            0.0.1-SNAPSHOT

                            compile

                                    

                  

        

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
