Hello,
On Windows I do this (simplified but works):
from("direct:exec").to("exec:cmd?args=/C echo echoString" ).to("mock:exec");
That is the exec is my command interpreter, and echo is an argument to the
interpreter.
(On Windows I need the /C otherwise I just get the data from starting the
cmd.exe)
