[mojo-user] jruby-maven-plugin: how to pass commandline arguments using the jruby:run goal?

[Torben Knerr]

Hi all,

just discovered the jruby-maven-plugin and it does exactly what I need --
simply executing a small ruby script :)

Even though it is not the recommended approach, I have used the 'jruby:run'
goal to invoke the script because of it's simplicity.
However, I was not able to pass any commandline arguments to the scripts
ARGV variable. Is that possible at all using the ruby:run approach?

Ideally I wanted to call something like 'mvn jruby:run -Darg1=val1' and then
pass the java system property as a commandline arg to the ruby script, but
it did not work this way :(

Any suggestions are welcome.

Thanks and regards,
Torben
