I have the same issue

[John Vilk]

I've confirmed and reproduced the issue! I'll take a look when I have time. Thanks for reporting.

[John Vilk]

Oof, this is an unfortunate non-error message.

You're actually specifying your classpath incorrectly! If you try:

java -cp docs/examples/example example.App

...notice that it doesn't work. Instead, you need to do:

java -cp docs/examples example.App

Thus, run the following command instead:

../../doppio -cp docs/examples example.App

With that said, this should really give you a better error message!

[Tadeusz Jordan]

Thank you a lot for a quick reply! It worked!

[Hung Huynh]

yes that was it. Though if you're inside the docs/examples folder, the correct command is:

%> ../../doppio -cp . example.App
