Sources JAR in Maven

[0x3333]

Source JAR in Maven doesn't include the Kotlin sources:

What I've found both the sources and the javadoc plugins don't support kotlin so for pure kotlin projects dummies need to be provided when delivering to maven central.

What about the includes directive to Apache Maven JAR Plugin?

https://maven.apache.org/plugins/maven-jar-plugin/examples/attached-jar.html

  Specify a list of fileset patterns to be included or excluded by adding <includes>/<include> or <excludes>/<exclude> and add a classifier in your pom.xml.
