scala(1)win7 Envirenment and Introduction

1. build the envirenment
download the related files:

http://www.scala-lang.org/downloads/distrib/files/scala-2.9.1.final-installer.jar
http://www.scala-lang.org/downloads/distrib/files/scala-2.9.1.final.zip

download the latest eclipse
http://download.actuatechina.com/eclipse/technology/epp/downloads/release/indigo/SR1/eclipse-jee-indigo-SR1-win32-x86_64.zip

It is said that eclipse 3.7 is not perfect supported. I still try the latest plugin with latest eclipse:
http://download.scala-ide.org/releases-29/stable/site

Unzip the file scala-2.9.1.final.zip to directory D:\tool\scala-2.9.1.final.

Add SCALA_HOME to system configuration. Add D:\tool\scala-2.9.1.final\bin to path in system.

Verify the installation with this command.
>scalac -version
Scala compiler version 2.9.1.final -- Copyright 2002-2011, LAMP/EPFL

>scala
scala>1 + 2

2. Try the first example with hello world
create a textual file with name hello.scala, the content is as follow:
object HelloWorld{
def main(args: Array[String]){
println("Happy Valenten's Day, Kiko.")
}
}
D:\work\scala>scala hello.scala
Happy Valenten's Day, Kiko.

3. Try with my IDE eclipse 3.7
After install the scala plugin, I will create the first scala project named easyscala. Then create the package named com.sillycat.easyscala.

After that, create a scala object named Love under that package. The codes are like this, and we can run as scala application in eclipse:
package com.sillycat.easyscala

object Love {

  def main(args: Array[String]) {
    println("Happy Valenten's Day, Kiko.")
  }

}
