maven Apache junit Ant UP

maven2是在ant的基础上发展起来的，并对ant的功能进行了进一步扩充，下面将说明如何利用maven2自动生成工程结构。

要使用maven2，首先需要在apache的官方网站下载最新版的工具：

http://maven.apache.org/download.html

接下来就是配置环境变量

设置 MAVEN2_HOME --------》D:\maven2（指向你的maven2的安装后根目录）

设置path ----------------》D:\maven2\bin;

接下来准备开始建立项目：

新建一个文件夹作为工作目录： D:\mywork

1.在命令行执行如下指令：

mvn archetype:create
-DarchetypeGroupId=org.apache.maven.archetypes
-DgroupId=com.mycompany.app
-DartifactId=my-app

切换到工作目录，这时你就会发现我们的工程框架已经建立好了

2.生成的pom（pom.xml）文件如下

<project pom="" maven.apache.org="" http:="" xmlns="&lt;a href=">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>com.mycompany.app</groupid>
<artifactid>my-app</artifactid>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>my-app</name>
<url>http://maven.apache.org</url>
<dependencies>
    <dependency>
      <groupid>junit</groupid>
      <artifactid>junit</artifactid>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
</dependencies>
</project>

3.下面用maven2开始编译工程：

mvn compile

运行结果如下：

[INFO] ----------------------------------------------------------------------------

4.开始为工程打包

mvn package

执行结果如下：

D:\mywork\my-app>mvn package

生成文件如下： my-app-1.0-SNAPSHOT.jar

5.将jar包放入资源库中执行如下命令：mvn install

执行结果如下：

其中的关键部分如下：

Installing D:\mywork\my-app\target\my-app-1.0-SNAPSHOT.jar to C:\Documents and Settings\abcd\.m2\repository\com\mycompany\app\my-app\1.0-SNAPSHOT\my-app-1.0-SNAPSHOT.jar

说明你刚刚生成的jar包已经放到了%userhome%\.m2\repository\
