从版本5开始,“枚举”是一个关键字,不能用作标识符

我将枚举用作参数,但出现此错误

error: as of release 5, 'enum' is a keyword, and may not be used as an identifier

private final kotlin.jvm.functions.Function1<com.tylertech.newworld.mobility.enum.CustomAlertDialogEvents, kotlin.Unit> itemClicked = null;

下面是我的枚举类

 enum class CustomAlertDialogEvents(var resId: Int, val value: Int) {
    ACTION_OPEN_SETTINGS(R.string.open, 0),
    ACTION_CLOSE_SETTINGS(R.string.close, 1),
}

我正在这样使用

private val itemClicked: (CustomAlertDialogEvents) -> Unit

任何想法为什么会出现此错误?
