Using SBT 0.10.1, Eclipsify for a new Scala project

Run sbt(0.10.1) in a new folder:

D:\samplescala>sbt

D:\samplescala>set SCRIPT_DIR=C:\util\sbt\

D:\samplescala>java -Dfile.encoding=UTF8 -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256m -jar "C:\util\sbt\sbt
-launch.jar"

[info] Set current project to default-097978 (in build file:/D:/samplescala/)

The following folders will show up under the root folder:

Create the default source/test/resource structure:

mkdir src\main\resources
mkdir src\main\scala
mkdir src\main\java
mkdir src\test\resources
mkdir src\test\scala
mkdir src\test\java

Create a build configuration file build.sbt, and place it in the root of the project with the following content:

name:="samplescala"

version:="1.0"

scalaVersion := "2.9.0-1"

libraryDependencies ++= Seq(
    "junit" % "junit" % "4.8" % "test",
    "org.scalatest" % "scalatest_2.9.0" % "1.6.1"
)

defaultExcludes ~= (filter => filter || "*~")

Add, one sample test in the file src\test\scala\gcdtests.scala, just to test out the sbt configuration:

package com.sample

object Gcd{
    def gcd(a:Int, b:Int):Int = if (b==0) a else gcd(b, a%b)
}


import org.scalatest.FlatSpec
import org.scalatest.matchers.ShouldMatchers


class GcdTests extends FlatSpec with ShouldMatchers{
    "GCD of 1440, 408" should  "be 24" in {
        Gcd.gcd(1440, 408) should equal (24)
    }
}

Invoke sbt, and run test, if everything is configured correctly the following output will be displayed:

D:\samplescala>sbt

D:\samplescala>set SCRIPT_DIR=C:\util\sbt\

D:\samplescala>java -Dfile.encoding=UTF8 -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256m -jar "C:\util\sbt\sbt
-launch.jar"

Now, to import this project into eclipse. Create a build.sbt file with the following contents and place in the project/plugins folder:

libraryDependencies <+= (libraryDependencies, sbtVersion) { (deps, version) => 
    "de.element34" %% "sbt-eclipsify" % "0.10.0-SNAPSHOT"
}

Restart sbt, if the plugin is configured correctly, eclipse will be a valid task in sbt, running this will create the .project and .classpath files for Eclipse:

> eclipse
[info] Starting eclipse
[info] written .project for samplescala
[info] written .classpath for samplescala
[info] * Don't forget to install the Scala IDE Plugin from http://www.scalaide.org/
[info] You may now import your projects in Eclipse

Assuming that Scala IDE for Eclipse is installed, import this new project into Eclipse:
