Subject Re: building a jar from groovy script with gradle
Date Tue, 08 Mar 2016 14:30:28 GMT
I have a similar situation I am about to tackle, building an installer that
executes Groovy code. This will be going to clients and run on windows, so
it really has to be an EXE.

Anybody have good experience with JAR-to-EXE packers or something?
