I've "deployed" some scripts to other users in my organization where Java but not Groovy is installed through the GroovyWrapper script. I got it from Codehaus and I can't find the original copy anywhere but I found a fork of it at https://github.com/sdanzan/groovy-wrapper that appears to have more features than the original. The original I have basically just uses the Ant inside of the Groovy distribution to compile a single Groovy file and merge that file, embeddable groovy JAR and some of the Groovy libs into a single jar you can run with java -jar.
Looking at the code it appears the main difference in that updated script is that it supports adding @Grab'd dependencies into the single JAR, presumably to prevent users from having to download them.

I have been trying to make a user executable jar but as 2 diff.jars. One jar is only my code, no support jars and 2nd is mystuff-all-v1.0.jar as a bundle w/all dependency jars included hence runnable. End user can choose jar. Are there other strategies to package code 4 deployment? Thx.
