Using Ivy launcher, passing arguments to launched class.
Hello,
I have the following problem:
I want to launch my main class using Ivy launcher as documented in Ivy
manuals:
java -jar ivy.jar -main com.my.MainClass
My main class expects parameters from command line in the format:
-paramName:paramValue
I try using Ivy launcher with -args option which is documented as follows:
-args <args> the arguments to give to the launched process
java -jar ivy.jar -main com.my.MainClass -args -param1:val1
However Ivy is not able to pass such a parameter into my class as it
interprets it as Ivy parameter which is not recognized printing:
Unrecognized option: -param1:val1. (message from Ivy launcher)
So if I try what follows (remove "-" from my parameter):
java -jar ivy.jar -main com.my.MainClass -args param1:val1
Ivy passes param1:val1 as argument to my main however my application
does not recognize it as it expects its all parameters to start with "-"
just as Ivy launcher does.
I think this is either a *BUG* or I am missing something. It seems Ivy
launcher interprets values after -args beginning with "-" as another
Ivy parameters. Is any way to pass parameters starting with "-" to the
launched class? Please help.
Best regards.

Looking at the code, it does appear that this case hasn't been handled.
I am not part of the Ivy dev team so I can't say whether this is a bug
or whether this was never thought of as a usecase. Perhaps you could
wait for someone from the dev team to respond or maybe file an enhancement.

Yes I tried in double and single quotes. The effect is that theses
quotes are passed as part of command line arguments to launched class
so without modification of launched class to strip off theses quotes it
still does not work. I think it is a common case that applications have
parameters starting with "-" and not expecting quotes in values of
command line arguments. It looks to be a bug in Ivy. So far I have no
work around to it.
Regards.

Have you tried to enclose those parameters in double quotes:
java -jar ivy.jar -main com.my.MainClass -args "-param1:val1 -param2:val2"
