Notes:

• The file name has to end in .main.kts and kotlin-main-kts.jar has to be on classpath. See https://youtrack.jetbrains.com/issue/KT-27853
• Transitive dependencies have to be explicitly listed, and version conflicts manually resolved by hard-coding the right versions.

kotlinc: https://kotlinlang.org/docs/tutorials/command-line.html

To edit this in IntelliJ IDEA:

• create and idea folder next to the .kts file
• save build.gradle to that folder
• import the project from idea/build.gradle.
