I follow the process stated in this article, https://kotlinlang.org/docs/tutorials/command-line.html in WSL Ubuntu 06.04. on the part of sdkman.
successfully installed all the requirement, sdk and kotlin and java jdk.
But when I try to run my first Hello world using this keyword.
kotlinc Hello.kt -include-runtime -d Hello.jar
error: no class roots are found in the JDK path: /usr/lib/jvm/java-9-openjdk-amd64
what to do with that?
