[wildfly-dev] Swarm "Could not find or load main class"

[Markus Eisele]

Hi,

The output doesn't contain a single org.jboss class being loaded. Also it
does not contain the jar itself.
So,  technically speaking this can't work. But why? The command isn't
exactly complicated.

Any further ideas?
Thanks,
Markus

redirect the output to a file since with that -verbose:class option, the
output can potentially be huge.
