In my Decompose library, I see that starting from Kotlin version 1.4.20 the maven-publish plugin uploads jar files for root packages (named without any a suffix). But there is no sources.jar uploaded. As a result I can't enable JCenter sync, since sources are mandatory for packages with jars .
E.g. this package has a jar file but does not have sources.jar file: https://dl.bintray.com/arkivanov/maven/com/arkivanov/decompose/decompose/0.1.4/
But e.g. this coroutines package has everything: https://jcenter.bintray.com/org/jetbrains/kotlinx/kotlinx-coroutines-core/1.4.2/

Questions:
1. Why there is no jar files uploaded for this package prior to Kotlin 1.4.20? (e.g. here). If there is no jar then it's ok to not have sources.jar.
2. Why there is no sources.jar uploaded in this case. Sources are uploaded fine for other non-root packages, e.g. the decompose-jvm.

I believe no sources jar is a bug with kotlin multiplatform & kotlin 1.4.21. I was able to include the sources jar manually to my common target by appending the artifact generated by metadataSourceJar gradle task in the publishing config

val kotlinMultiplatform by getting {
    artifactId = "project-id"
    artifact(tasks.getByName("metadataSourcesJar")) {
        classifier = "sources"
    }
}

Thanks! Looks like this helps.
