Embed dependencies brake Kotlin projects compilation

[dlecan]

Hello,

I wonder why the Kotlin runtime is packaged with this "fat" jar.
It leads to compilation errors:
w: Some JAR files in the classpath have the Kotlin Runtime library bundled into them. This may cause difficult to debug problems if there's a different version of the Kotlin Runtime library in the classpath. Consider removing these libraries from the classpath
Then it breaks compilation.

Look at the content of the jar:

https://repo1.maven.org/maven2/com/smartcar/sdk/java-sdk/3.2.1/java-sdk-3.2.1.jar

Is it possible to download somewhere only the com.smartcar.* jar ?

If I tried 3.1.1, it also breaks my application :-(
Useless

Hi @dlecan 👋

I ran gradle dependencies which shows that Kotlin is being bundled in by Okio which itself is bundled in by Okhttp. We can take a look at how to go about publishing a jar which just has the com.smartcar.* classes next week, but I'll be up front and state that I'm not too familiar with Java packaging. If you know how to achieve this feel free to push up a PR and we can review it.

Was it intended to publish a fat jar?

This line is breaking everything:

java-sdk/build.gradle

Line 88 in 1b365bb

configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }

Is there any update on this? I can't upgrade past 3.1.0 as 3.1.1 breaks my build. I'm using kotlin 1.9.23 and it looks like there is a conflict there.
