配置文件的介绍 Maven 2.0 竭尽所能的确保构建是可移植的.此外,这意味着允许构建配置在POM中,绕过所有文件系统引用(在继承,依赖以及其他方面),并学习更多用本地仓库来存储必要的元数据来使一切成为可能. 然而,有时候可移植性并不能完全实现.在某些情况下,插件可能需要使用本地文件系统路径来进行配置.另一些情况下,可能需要一个略有差别的依赖集合,而且项目的工件名称可能需要轻微的调整.还有一些情况下,根据你的构建环境你甚至可能需要包含整个插件在构建生命周期中. 为了处理这些情况,Maven 2.0 引进了构建配置文件的概念.配置文件被指定使用来自POM本身的可用元素的子集(加上一些额外的部分),而且可以通过多种不同的方式来触发.它们在构建时期修改POM,这意味着它们使用补集来为一组目标环境提供相同但又不同(equivalent-but-different)的参数(例如,提供应用服务跟路径在部署,测试,生产等环境).这样,来自你项目组的不同成员的配置文件就可以轻易的产生不同的构建结果.然而,恰当的使用配置文件依然可以保持项目的可移植性.这也会最小化maven -f选项(这个选项允许用户用不同的参数或者配置来创建不同的用于构建的POM以提高可维护性因为它只依托于一个POM运行)的使用. 配置文件的不同类型?它们在哪里定义? 每个项目 -定义在POM本身(pom.xml) 每个用户
