I am trying to run an HelloWorld kind of program for Scala , in Intellij.

My code is:

package helloscala

object HelloScala { def main(args: Array[String]) { Console.println("Hello, world!"); } }

I am clueless about the error , that is prompted by the INtellij IDE.

 JDK is JDK5

Error is:

java.lang.UnsupportedClassVersionError: Bad version number in .class file at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$100(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:268) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Exception in thread "main"

Any input would be great.

Is there any particular reason that you are using Java 5? If not then just install a newer JDK. – maba
Well my current code base is Java 5. I don't want to risk that – user1993412
@user1993412 what scala version are you using? – om-nom-nom

Scala 2.10 doesn't support Java 5.

Software Requirements: The Scala software distribution can be installed on any Unix-like or Windows system. It requires the Java runtime version 1.6 or later.

Use JDK 7 + sbt-idea plugin.

SBT is the preferred build tool

I recommend my project skeleton for setting it all up. Intllij + SBT (+eclipse if you so want to)
