NotImplementedException class override message field in Exception class #3

Closed MaXal closed 10 years ago

MaXal commented 10 years ago 
Error:(6, 31) Kotlin: Accidental override: The following declarations have the same JVM signature (getMessage()Ljava/lang/String;):
    fun <get-message>(): kotlin.String
    fun getMessage(): kotlin.String?

I just got this exact error message when I went to run the first unit test of the Kotlin Koans. Using IntelliJ IDEA 13.1.3

To fix this you need to change field in NotImplementedException to something like:

class NotImplementedException(val message1: String): Exception(message1)

Thank you for the reply. I made the change you suggested and the unit test now compiles and runs.

Should this change be made in the github repository or am I using some combination of tools and libraries that causes the error to occur?

Thanks again.

MaXal commented 10 years ago

Yes, I believe this change should be in the repository and it's not connected to environment.

I've updated the code. The problem occurred because we started to report platform signature clashes (http://blog.jetbrains.com/kotlin/2014/07/m8-is-out/).
