Maven让项目管理更轻松（一）待续

1.Maven概述

当您的项目逐渐变得庞大和复杂时，最好使用一种构建工具来自动构建您的项目。例如，一个典型的java项目，每次构建时都要经历编译java源代码，把class文件打成.jar包，生成javadocs文档等步骤。这些步骤都可以用构建工具帮您自动完成。说到构建工具,大家肯定都知道make，但make是依赖具体操作系统的。Java-centric选择了Ant，一种可以跨平台的使用xml来替换Makefile糟糕语法的构建工具。
    来自Apache软件组织的构建工具Maven更可能成为您的选择，Maven不仅提供了out-of-the-box的解决方案来统一处理构建相关的任务，还提供了信息统计的功能。使您的开发团队可以更好地跟踪项目的进展情况。

Maven具有以下功能：

（1）产生Javadoc文档
（2）运行unit测试
（3）源代码文法分析
（4）产生违反团队编码规范的详细报告
（5）产生CVS最新提交报告
（6）产生CVS更改最频繁的文件报告和提交最频繁的开发人员报告
（7）产生可以交叉引用的HTML格式的源代码，等等。

2.Maven软件下载

Maven软件下载可以到 http://maven.apache.org/download.html

笔者使用的为 Maven 2.0.4

3.Maven软件配置

1。创建d:\project目录，将已下载的Maven软件解压到project目录下

2。设置MAVEN_HOME＝D:\project\maven-2.0.4

3。设置path 在path中加入 ;%MAVEN_HOME%\bin

运行m2.bat mvn.bat出现以下提示则表明设置成功了！

[INFO] Scanning for projects...
     [INFO] ------------------------------------------------------------------------
     [ERROR] BUILD FAILURE
     [INFO] ------------------------------------------------------------------------

     [INFO] Final Memory: 1M/2M
     [INFO] ------------------------------------------------------------------------
4。设置 Local Repository（此处和2.0.4以前的版本有所不同）

找到D:\project\maven-2.0.4\conf下的settings.xml文件

在<settings>后加入 <localRepository>c:\project</localRepository>

即可

5.设置server

在conf下的settings.xml加入

<server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>
      <server>
      <id>siteServer</id>
      <privateKey>c:\project\server</privateKey>
      <passphrase>optional; leave empty if not used.</passphrase>
    </server>

4.实施操作

（1）运行

进入command，运行下面命令：mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app出现以下信息
