搭建eclipse+maven+scala-ide的scala web开发环境

http://www.tuicool.com/articles/NBzAzy

江湖传闻，scala开发的最佳利器乃 JetBrains 的神作 IntelliJ IDEA ，外加构建工具sbt 是也。

但因历史原因，项目组成员对 Eclipse + Maven 组合更为熟悉，为了快速实现项目原型，不增加不确定因素带来的风险，搭建一套 Eclipse + Maven + Scala-IDE 的开发环境。

基本原则是，必须完全满足但不限于以下几点内容：

• 方便重构，方便调试，支持热部署。
• 可直接使用已有maven的本地和私服仓库。
• 可以无束缚的只用自己熟悉的语言编写代码。
• 可以快速混合编译scala+java代码，包括交叉引用的文件。

如果你有洁癖，可以自己下载 Eclipse ，然后安装各种插件。但是可能会遇到插件依赖包版本冲突之类的问题，为了速度，我直接下载官方打包好的 Scala-IDE ，有各种平台可供选择。

使用 Git 管理项目源代码，需要安装 EGit 插件，Eclipse插件更新地址 EGit Updates 。

假设项目名称为 feeling ，使用 JDK 1.7，Servlet 3.0，最终目录结构如下。
