Intellij下利用Maven构建Scala Project

利用Intellijidea直接创建scala工程很容易，但现在主流开发环境大多采用Maven构建，而且有个好处是java和scala可以在一个项目中混合使用。

1. 安装Scala插件

File -》Settings -》Plugins，在搜索栏里搜索“scala”，会有两个，SBT和Scala，安装Scala。

2. 新建Maven项目

File -》New -》Project，选择Maven，在右边选择scala，如图

3. 修改scala版本

一路确定，最终会生成Maven项目，并会从网络上下载所需的dependencies；这里需要把scala版本改成自己的版本，在“pom.xml”里修改：

 <properties>    <scala.version>2.11.7</scala.version>  </properties>

查看本机scala版本的方法：命令行里：scala -version

这样就构建好了，需要等待项目下载dependencies，如果pom.xml开始报错也没事，修改完scala的版本号后等待更新完成。
附一个默认的只修改了scala版本的pom.xm内容：
