public static void main(String[] args) {
sourceHandling.Compiler.main(args);
}
}


The editor does complain about the syntax, but it builds fine.

You then have to add scala-library.jar to the project as an “external JAR” before export.

The java file fails to run in Eclipse with error:

no such file: vg.os.ScalaMain

If I jar it up it fails to run with:

chris@vostro:~$ java -jar scalatest.jar

Any idea what silly mistake I’m making?

Thanks,

Main.java:

package vg.os;

import java.util.ArrayList;

import scala.tools.nsc.MainGenericRunner;

public class Main {
public static void main (String[] args) {
ArrayList argList = new ArrayList();
argList.add(”vg.os.ScalaMain”);
for (String s : args) {
argList.add(s);
}
MainGenericRunner.main(argList.toArray(new String[0]));
}
}

ScalaMain.scala:

package vg.os

object ScalaMain {
def main(args : Array[String]) : Unit = {
println(”hello world from ScalaMain”)
}
