why does running jars from the command line with kotlin not include the standard java libraries?

Normal jars don't bundle their dependencies with them (so you can install them separately if you have a package system). You can either use gradle's distZip task to get a ZIP with properly configured classpath, or if you really want a single JAR you can use a Uber-Jar generator (for example the ShadowJar Gradle plugin)

I suggest you use ShadowJar

@Łukasz Bednarczyk what's the difference . I am using distZip task for now. Is there any performance hit using this method ?

[Łukasz Bednarczyk]

@subashz to be honest, I always use ShadowJar, and I have never got any problem.

Yeah, found some interesting article after thinking about it. https://devsday.ru/blog/details/50822

@subashz distZip/distTar gives you a run script as well, while ShadowJar expects you to run it with java -jar. If you're sending it to an end user, it's probably easier/more native to use those.

@CLOVIS ok, but in backend app it isn’t so important
