如何解决或诊断呢？

Answer 1:

您应该删除compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"从你的dependencies部分，并将其移到buildscript { dependencies { ... } }

Answer 2:

你没把compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"在错误build.gradle文件

您可以使用kotlin插件的内置的转换器来处理这个问题。据Kotlin Docs ：

在项目配置科特林
当添加新的科特林文件，IntelliJ IDEA的（和Android工作室）会自动提示我们，我们是否要配置科特林运行的项目。然而，目前，将现有的Java文件不提示此操作。因此，我们必须手动调用它（通过查找动作）：

然后，我们会提示科特林的版本。选择最新的从已安装的版本列表。

我们配置科特林后，该应用程序的build.gradle文件应该被更新。现在我们可以看到，应用插件：“科特林-机器人”，加入的依赖关系。
（有关详细信息如何设置为gradle这个项目，请使用摇篮）
做的最后一件事是同步的项目。我们可以按Sync Now在提示或调用操作同步工程与摇篮文件 。
