Hi, in a situation like this: https://pl.kotl.in/vK8g6iJtG is there a way to implement this interface while keeping the

username

part of the primary ctor and without changing its name?

If the interface is defined in Kotlin, you should instead declare a property instead of a getter, then overriding it is simple:

interface Foo {
    val username: String
}

data class User(override val username: String): Foo

unfortunately its defined in java

Ah if it's Java then it will indeed be a problem, see: https://youtrack.jetbrains.com/issue/KT-6653

funny, thats even the very same interface i have problems with 😄

You could use

@get:JvmName("getUsernameKt")

on the constructor parameter to avoid that conflict with the getUsername override method.

@Nick Allen awesome, thank you!
