Преобразование Java-файла в Kotlin теперь не будет компилироваться - «Внутренняя ошибка компилятора»

Question

Я работаю над преобразованием проекта Java Android в Kotlin в Android Studio, и у меня возникают проблемы.

Это работало нормально, когда я преобразовал один файл в Kotlin с MainActivity, все еще работающей на Java, но после преобразования MainActivity код больше не компилируется. Он завершается с ошибкой, связанной с Gradle / Kotlin, а трассировка стека не очень полезна и не указывает ни на что в моем коде.

Источник MainActivity.kt

Есть идеи, пожалуйста? Вот трассировка стека:

Проблема заключается в преобразовании OnClickListener с. Я проверил ваш код и обнаружил, что компилятор kotlin не может определить его лямбда-форму. Попробуйте изменить OnClickListener s следующим образом:

@Suppress("ObjectLiteralToLambda")
class MainActivity : Activity() {

    // private val randomFactListener = OnClickListener {
    //    // code block
    // }

    private val randomFactListener = object : OnClickListener {

        override fun onClick(v: View?) {
            // code block
        }
    }

    // private val backToHomeListener = OnClickListener {
    //    // code block
    // }

    private val backToHomeListener = object : OnClickListener {

        override fun onClick(v: View?) {
            // code block
        }
    }

    // private val anotherRandomFactListener = OnClickListener {
    //    // code block
    // }

    private val anotherRandomFactListener = object : OnClickListener {

        override fun onClick(v: View?) {
            // code block
        }
    }

}
