Question

I have a simple Scala project that runs without any problems inside Eclipse, however, when packaged into a .jar I receive this exception when running it:

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: scala.util.matching.Regex.replaceAllIn(Ljava/lang/CharSequence;Lscala/Function1;)Ljava/lang/String;

What is going on here?…

The code line in question, and the full stack are below.

This is the offending line:

"alt=\"[^>]+\">".r.replaceAllIn(inputStr, {_.replace(">", "/>")})

Full stack:

Found out what’s wrong, Eclipse is using a scala-library.jar from:

C:\eclipse\configuration\org.eclipse.osgi\bundles

and for some reason the jar I copied from Scala’s installation folder is not the same.
Fixed by using the same scala-library.jar that Eclipse is using.
