Does not work with Kotlin 2.0.0 #421
Description
Activity
Same issue here.
Got the same error
I will try to solve it, although I don't have much time to invest. Contributions from anyone are more than welcome.
I have investigated the issue. The problem with version 2.0 is that it completely changes how the scripts are executed. The current way of executing the script is by wrapping it with the following code:
But now, this method does not work anymore.
I was also thinking about a more sophisticated way of rewriting the script so that it is put inside
fun main() {}
block. But it will only work for some cases - for example,enum class {}can not be defined in the function's local scope, so it will fail if you try to define an enum in your script.The only possible alternative I can see is to use the Kotlin script engine to implement the KScript engine. I have started the branch with those changes, but I don't have time to accomplish that work:
If anyone wants to take on this task, feel free to do so. I will accept the MRs.
kscript is excellent and missing feature. it has to be upgraded to support koglin 2+, as many new code won't run with older versions, while kotlin's scripting itself is yet practically unusable. Thanks for incredible tool anyway... it was a great time using it.
Reacted by Doğaç Eldenk and Luong Vo (Lucas)For others facing this issue, I faced a slightly different error message:
Exception in thread "main" java.lang.ClassNotFoundException: kscript.scriplet.ClientAs a workaround, until there is kotlin 2.0 support, you can downgrade the kotlin version using sdkman:
sdk install kotlin 1.9.24For me, it doesn't work with
1.9.24either 🤔Macbooc M2 Pro (arm)

It seems kscript does not work with Kotlin 2.0.0. What I observe is the same as #408:
It works well with Kotlin 1.9.24 (after cache removal).
