安装

1

 sudo apt-get install maven2

功能

Maven作为Apache的一个开源项目，旨在给项目管理提供更多的支持，主 页地址为Maven2 它最早的意图只是为了给apache组织的几个项目提供统一的开发、测试、打包和部署，能让开发者在多个项目中方便的切换

  • 项目标准化
  • 文档和报告
  • 类库管理
  • 发布管理

依赖库管理及目录

pom.xml格式以及使用

相关命令

使用

自己实验使用步骤

根据模板创建工程

可以使用

1

mvn archetype:generate

进行创建，但是太多模板，无法选择，需要利用过滤器缩小list。比如我只需要最基本的模板，输入下面的命令

1

mvn archetype:generate -Dfilter=quick

输出

根据包结构调整源码目录

添加依赖

因为项目依赖于Apache Mina以及log4j等，在pom.xml中添加如下字段

5指定jdk版本

因为截至我使用的Maven 2.2.1 版本默认是利用jdk1.4进行编译，部分新特性无法用到，需要人工指定jdk版本，在pom.xml中添加

指定1.6版本进行编译

运行时依赖

利用

1

java -cp target/PSClient-1.0.jar com.cloudtv.PSClient.TestClient

编译打包正确，但是运行时出现错误，看提示应该是没有找到依赖的jar包.解决方式 有两种，一种是打包为war包，然后利用tomcat进行发布；另一种是将依赖包也打入 相应的路径，还是jar包，只不过需要早pox.xml中的plugins下面添加子字段
