kotlin - How to overcome "same JVM signature" error when implementing a Java interface?

Question

With the code below, I am getting the following error in IntelliJ IDEA 13.1.6 and Kotlin plugin 0.11.91.AndroidStudio.3:

Platform declaration clash: The following declarations have the same JVM signature (getName()Ljava/lang/String;):
  ? public open fun getName(): kotlin.String?
  ? internal final fun <get-name>(): kotlin.String?

Java class, JavaInterface.java:

public interface JavaInterface {
  public String getName();
}

Kotlin class, KotlinClass.kt

public class KotlinClass(val name: String?) : JavaInterface

I've tried overriding the 'getter' method by adding override fun getName(): String? = name, but that produces the same error.

I can see one workaround by doing this instead:

public class KotlinClass(val namePrivate: String?) : JavaInterface {
  override fun getName(): String? = namePrivate
}

But in my real-world case I have a number of properties to implement and need setters too. Doing this for each property doesn't seem very Kotlin-ish. What am I missing?

Answer 1

Making that variable private solves the problem.

public class KotlinClass(private val name: String?) : JavaInterface
