Running kts-script from Maven

Support
1

Hello,

I would like to run kts-script from Maven.

The obvious way would be to download kotlin-compiler.x.x.x.jar and run

 kotlinc -script my-script.kts

from maven. But then I would have to locally install and keep up-to-date kotlin compiler on all the machines…

Instead it would be great to use kotlin jar from the Maven repository and call kotlin compiler using exec-maven-plugin:java maven plugin. But unfortunately, I can’t get it to work. Please see https://stackoverflow.com/questions/64871438/run-kotlib-kts-script-from-maven .

Are there other ways of achieving this goal?

Ahy help is very appreciated :slight_smile:. Thank you!

Cheers,
Boris Brodski

Perhaps you could use the script goal of the Kotlin Maven plugin, like in this example: kotlin/pom.xml at 1.4.0 · JetBrains/kotlin · GitHub
The script can be provided inline or in a file beside: kotlin/pom.xml at 1.4.0 · JetBrains/kotlin · GitHub

Thank you! This is exactly, what I have been looking for (y)

It works but it throws a WARNING with the stacktrace below. Is there any possibility to prevent the stacktrace from been printed?

Thank you!

If you have a stable reproducer, please report it to https://kotl.in/issue.

Sometimes setting idea.io.use.nio2=true system property helps, so you can try to pass it to the mvn command with -Didea.io.use.nio2=true command line parameter

This problem still happens today with Kotlin 1.7.20, along with another warning. I reported it as https://youtrack.jetbrains.com/issue/KT-54461/Warnings-and-stack-traces-when-executing-scripts-via-kotlin-maven-plugin, including a reproducer project.

export MAVEN_OPTS=-Didea.io.use.nio2=true does prevent the original exception. Thank you for the suggestion @ilya.gorbunov !
