When running HelloWorld example following exception occurs:

It works for me. Can you confirm you use windows or linux?

Which JVM do you use (JVM 8 ?)

Can you try in cleaning all kevoree artefacts in your .m2

Regards

Environment: Windows 8.1 java -version java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Deleted all org.kevoree in.m2 and tried again, still same result :-(

[maxleiko]

Can you try with a JDK 8 ?

Hi,

Issue is solved :-) The POM declared the GruopID org.kevoree.sample while the code asked for org.kevoree.example. Changed GroupID to org.kevoree.example in POM and checked in.
