Scala混合项目Maven打包

IDEA Java/Scala混合项目Maven打包1.在建立Maven项目时，选择骨架为maven-archetype-quickstart2.pom文件内容为：<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>scalalearn</groupId><artifactId>scalalearn</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><name>scalalearn</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><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>2.11.6</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><archive><manifestFile>src/main/resources/META-INF/MANIFEST.MF</manifestFile></archive></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions></plugin></plugins></build></project>3.在src/main下新建scala文件夹，用于存放scala源码，并在project structure中将其设为source目录；在src/main下建立resources/META-INF目录，并建立MANIFEST.MF文件，在里面填入mainclass，并将resources目录设置为资源目录Main-Class: com.scalalearn.java.main.App4.设置之好的项目结构如图所示：5.com.scalalearn.scala.main.ScalaPrint.scala的内容为：package com.scalalearn.scala.main/*** Created by Administrator on 2016/5/14.*/object ScalaPrint {def print（）:Unit={println（"I love scala"）;}}
com.scalalearn.java.main.App.java的内容为： package com.scalalearn.java.main;import com.scalalearn.scala.main.ScalaPrint;/** * Hello world！ * */public class App {public static void main（ String[] args ） {ScalaPrint.print（）;}}6.打jar包的mvn命令为：mvn clean scala:compile compile package7.最后会在target目录下生成两个jar包，分别为：scalalearn-1.0-SNAPSHOT.jar和scalalearn-1.0-SNAPSHOT-jar-with-dependencies.jar8.运行jar效果如下：本文永久更新链接地址：http://www.linuxidc.com/Linux/2016-08/134137.htm
