A modern programming language that makes developers happier.

kotlinlang

1. Are args for running Gradle itself
2. Is also just looked at by start scripts like the wrapper
3. Is for compiling java, that can never help for compiling Kotlin
4. Sounds reasonable except that you give `--add-opens,java.base/java.util=ALL-UNNAMED`, this is most likely not correct. I wonder that it did not complain about that syntax

Thanks! Still same error after changing to `"-Xjavac-arguments=--add-opens=java.base/java.util=ALL-UNNAMED"`

Somehow these arguments are not  reflected on kotlin compiler daemon

Which also is not the right syntax I think.
But if it does not complain about the syntax it is probably not used, yes.

which part of the syntax is not correct `-Xjavac-arguments` option or `--add-opens`  ?

I think there has to be a space after `--add-opens`, but I'm not sure wheter equals sign might also work
