  1. POExporting Scala project as jar from Eclipse
    text
    copied!<p>I have a Scala project and I would like to export it as a jar.</p> <p>*1. At first I tried creating a Java class for the project as an entry point</p> <pre><code>public class JMain { public static void main(String[] args) { System.out.println("Java main calling Scala main"); SMain.main(new String[] {""}); //SMain.main is the actual *main* </code></pre> <p>and this worked fine and dandy when launched from Eclipse, but when I export it as jar it'll give me 18 exceptions or so. I do now know how to replicate then "environment" in which Eclipse manages to launch this and I'm prety sure it relies on the fact that Scala is on my system already - I need a self contained jar with everything packed in there.</p> <p>*2. My second try consisted of trying what <em>lach</em> suggested here <a href="https://stackoverflow.com/questions/2921600/how-to-deploy-a-scala-project-from-eclipse">How to deploy a Scala project from Eclipse?</a> namely:</p> <pre><code>public class JMain { public static void main(String[] args) { System.out.println("Java Main"); List&lt;String&gt; argList = new ArrayList&lt;String&gt;(); argList.add("fully.qualified.ClassName"); //??? for (String s : args) argList.add(s); scala.tools.nsc.MainGenericRunner.main(argList.toArray(new String[0])); </code></pre> <p>This time it won't even run from Eclipse, although it gives only 6 or so exceptions starting with the famous <strong>NoClassDefFoundError</strong>. I have a feeling I'm not getting <em>fully.qualified.ClassName</em> right. *3. If the <em>main</em> Scala class is called "Dis.scala" and is located in package "pack" shouldn't this <em>fully.qualified.ClassName</em> be "pack.Dis"?</p> <p>I'm using Jre 1.6 and Scala 2.9.2 EDIT: I have included all external imported jars, even scala-library.jar - everything is nice and packed in the jar</p> <p>P.S. I am not familiar with Ant or Maven or Sbt. I just want my Scala project jared - if possible without getting into hairy things.</p>
