Hi everybody,

I am trying to enter the wonderful world of Scala programming, but I can't manage to run a simple HelloWorld :-(

Please can somebody point me out where or what I got wrong? I have attached a a screenshot, hope that's OK.

Thanks in advance,

Sylvain

PS:

Error message translates as:

Error: Could not initialize main class MyPackage.HelloWorld in module module myProject

Caused by : module myProject: java.lang.NoClassDefFoundError

Can you retry with JDK 8? Apparently JDK 10 module system is getting in your way.

I think you need to add some parameters to java invocation, but I don't know the details - I haven't tried running Scala on JDK above 8 yet.

You could try googling about running legacy java applications on JDK 9/10/11 - the command line parameters should be the same.
