Claus Ibsen commented on CAMEL-22988:
-------------------------------------
camel-jbang is required/intended to be installed and use from the CLI as camel
and not to use jbang blah blah. The latter is for advanced use cases
> Camel JBang eval command cannot work without camel cli installed
> ----------------------------------------------------------------
