eclipse创建maven项目

1. 创建聚合模块（工程的父模块，应该是管理项目用的）。选择菜单项 File—>New—>Other，在弹出的对话框中选择Maven下的Maven Project，然后单击Next按钮，在弹出的New Maven Project 对话框中，使用默认选项，单击Next 按钮，此时m2eclipse 会提示我们选择一个Archetype。这里选择maven-archetype-quickstart，随后按照提示创建Maven聚合模块 app-parent,此处需要在pom文件中修改 <packaging>pom</packaging>。
2. 创建maven模块。app-common, app-main,过程同上。
3. 创建maven web模块 ,创建时选择Archetype时应选择 maven-archetype-webapp ,app-web
4. 在web模块的pom文件中添加依赖，并添加tomcat插件；
