eclipse+scala+java+maven 整合实践
一、軟件版本
Eclipse Mars.1 (4.5.1)
Apache Maven 3.3.9
二、下載scala plugin
1.在scala-ide.org網站上可以找到鏈接和下載地址
http://scala-ide.org/download/current.html
2.打開Eclipse，Help -> Install New Software（因網絡問題，這個沒裝成功，我下載以后本地安裝）
三、接下來創建Maven項目。
File->New->Maven Project，然后在項目上右鍵,configure, Add Scala Nature.
創建scala包
src/main/scala
項目結構如下圖
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、執行mvn命令
mvn clean scala:compile compile package
六、執行jar包
APP類
?
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args )
{
HelloJava.main(args);
HelloScala.main(args);
}
}
HelloJava類
?
?
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");
}
}
執行結果
