一、软件版本

Eclipse Mars.1 (4.5.1)

Apache Maven 3.3.9

二、下载scala plugin
1.在scala-ide.org网站上可以找到链接和下载地址

http://scala-ide.org/download/current.html

2.打开Eclipse，Help -> Install New Software（因网络问题，这个没装成功，我下载以后本地安装）
三、接下来创建Maven项目。
File->New->Maven Project，然后在项目上右键,configure, Add Scala Nature.

创建scala包

src/main/scala

项目结构如下图

四、增添POM配置

<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/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.jrj.jintui</groupId><artifactId>jintui-ml</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><dependency><groupId>org.scala-lang</groupId><artifactId>scala-library</artifactId><version>2.11.8</version></dependency></dependencies><build><plugins><plugin><groupId>org.scala-tools</groupId><artifactId>maven-scala-plugin</artifactId><version>2.15.2</version><executions><execution><id>scala-compile-first</id><goals><goal>compile</goal></goals><configuration><includes><include>**/*.scala</include></includes></configuration></execution><execution><id>scala-test-compile</id><goals><goal>testCompile</goal></goals></execution></executions></plugin><plugin><artifactId>maven-assembly-plugin</artifactId><configuration><descriptorRefs><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions></plugin></plugins></build></project>

五、执行mvn命令

mvn clean scala:compile compile package

六、执行jar包

APP类

/** * Hello world! * */public class App {    public static void main( String[] args )    {        HelloJava.main(args);        HelloScala.main(args);    }}

HelloJava类

package com.jrj;public class HelloJava {public static void main(String[] args) {System.out.println("hello java");}}

HelloScala

package com.jrjobject HelloScala {    def main(args: Array[String]) {      println("hello scala");   }}

执行结果
