It’s a java thing, not a groovy thing. That’s just what java -jar does.
You may be better off having groovy *installed* as opposed to invoking via a java command pointing at the jar. Then you can just use eg: groovy -cp . TestGroovy.groovy And as it’s being run as a script you don’t even need the class boilerplate in the groovy source. -- Rachel Greenham rac...@merus.eu > On 22 Nov 2021, at 12:09, Blake McBride <blake1...@gmail.com> wrote: > > Hi Paul, > > That worked great.
