maven-antrun-plugin

      ant是一个老牌的项目打包管理系统了，目前虽然已经慢慢被maven取代，但其功能的强大仍然是很多场合下的首选，尤其是众多的task可以基本满足任何需求。其实在maven中也有使用ant的需求，比如不同环境打包编译时使用不同的配置信息等，或者是说做一些文件删除、复制之类的事情，这有些是maven做不来的，而ant就可以了，况且maven中已经有了maven-antrun-plugin插件，专门为在maven中运行ant做好了准备。 

在项目的pom文件中定义如下插件片段：

这里，我们在maven的编译阶段执行一些文件的删除操作，比如将测试环境的配置文件删除，复制生产环境的配置文件等等，我们都可以使用ant的task来定义。通过ant的maven插件，可以将ant的强大功能也都引入到maven中来，实现二者的强强结合。
