Updating Kotlin and Gradle

Programming Kotlin

Would the maintainers be ok for me to look into updating the Kotlin and Gradle version for the Kotlin track?

While working on the when concept, I found the Kotlin version used by the track doesn’t support guard conditions (introduced in 2.2). I was also thinking to update Gradle at the same time as Gradle 8.4 can’t run in a Java 25 JVM.

FWIW the Java test runner uses gradle:9.5.0-jdk25@sha256:03305b464e024b29cfaad1c4a41fed61d06d15453176d2180f65bd4358b789a6. Reusing the same hash when reasonable to do so allows sharing layers and reducing storage costs.

Yes and yes.

@kahgoh I may not have said it before but you have perpetual permission to do this and more for Kotlin. Your work has been great.

I have just noticed that the kotlin version used in the Protein Translation exercise is 1.6.0. (I could not use data object for example).
The file settings.gradle.kts is I think setting the kotlin version to 1.6.0.

I opened the forum to look for relevant posts and found this one. I think that updating the Kotlin version would be very useful. Thank you for your effort.
