Hey devs, so I got a problem with creating a fat jar in my project since we I converted the Gradle config from GroovyDSL to KotlinDSL. We used to use the shadowJar plugin, but according to what I googled so far, there should even be a solution without it. So I converted (with the help of Stackoverflow) the Groovy solution (of how to configure the jar-plugin). But gradle clean build still doesn't create a fat jar (but at least the main-class is set). Here is the Stackoverflow ticket: https://stackoverflow.com/questions/55575264/creating-a-fat-jar-in-gradle-with-kotlindsl

Is suggest asking in #gradle. Or look at gradle docs under publishing. I seem to recall info there about fat jars. Can't do everything shadow plugin can, but likely what you need.

sounds reasonable 😅 but how do I contact the workspace admin in order to receive an invitation?

[Mike]

All channels are open, and you should be able to search/navigate channels to get there. cmd/ctrl-K is keyboard shortcut for navigating to, and searching for channels.

I thought there was more customization available, but can’t find it at moment. If all you want is the dependent jars, then they give an example under Example 7.

Highly recommend using the Shadow plugin ( https://imperceptiblethoughts.com/shadow/ ) to create a Fat JAR. The plugin works well with Kotlin DSL.

@Mike ah, you meant the kotlin.slack channel which i totally overlooked. I thought you meant the gradle.slack workspace 😂

@napperley Hi Nick, i'm fine with using shadowJar. That's how I started of actually. It failed to work after switching but now I'll check out your config. Thanks!

If all you need is to make a docker image out of it, google's jib is VERY easy to configure, just keep its plugin on top of all the others in the plugin block.
