java - ClassNotFoundException: HelloStageDemo -

the code i'm running homepage of http://www.scalafx.org. there no compiler warnings when runs exception. first tried using jdk 1.7 scala 2.11 , scalafx 2.9.3-2.2.67 , got equivalent error. still jdk 1.8 scala 2.11 , scalafx 2.11-8.0.20-r6. i'm hoping i'm stupidly missing simple. gets written console:

marsatomic , hot licks correct. how got work:

dragged file containing hellostagedemo src folder, marked sources root.

right-clicked on project node , selected "open module settings." clicked "dependencies" tab. clicked greenish plus sign , pressed come in "jars or directories..." browsed projects src folder , clicked ok button. compiling yielded scala-reflect errors. added scala\lib folder module dependencies in same way had src folder. compiled , ran.

thanks steering me straight!
