eclipse+scala+java+maven 整合实践

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>

<build>
<plugins>

<include>**/*.scala</include>
</includes>
</configuration>
</execution>
<execution>
<id>scala-test-compile</id>

</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>

<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.jrj
object HelloScala {
def main(args: Array[String]) {
println("hello scala");
}
}

执行结果
