is it possible to do this more elegant? Let these perhaps be generated, instead of having to write them all out

Alas, not that I know.

But you could do something like this:

class MyException @JvmOverloads constructor(
    cause: Throwable? = null,
    message: String? = cause?.toString(),
    enableSuppression: Boolean = true,
    writableStrackTrace: Boolean = true
)Exception(message, cause, enableSuppression, writableStrackTrace)

Where the @JvmOverloads guarantees Java compatibility.

thanks! but this still isn't ideal
It causes a problem when I don't put the message = there. It would ask for a Throwable instance

[bezrukov]

because JvmOverloads generates constructor per default parameters prefix.
In case above it generates four constructors
()
(throwable)
(throwable, message)
(throwable, message, enableSupression)

[bezrukov]

so calling
KotlinPluginException("message without named argument") is not working because there is no (message) constructor

[bezrukov]

you could swap message and throwable, but then there will be no (throwable) constructor.

So you need just add one more constructor by hands:
constructor(message: String) : this(null, message)

passing null as the cause in the constructor breaks the initCause function as well. not sure if you care
