1) 使用MVN创建项目

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

2）在项目目录src/mainz中创建scala目录，创建文件hallo.scala

object HelloWorld {

    def main(args: Array[String]) {

      println("Hello, world\!")

    }

  }

3）修改pom.xml编译scala文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

4) 编译、打包

mvn package

5）执行

scala ./target/my-app*.jar

环境：

fedora 18

scala 2.10

mvn 3.0

jdk 1.7
