最近，语法高亮显示在 Android Studio 中对我不起作用。
而且我认为这与我的项目有关，而不是 Android Studio 本身。
据我了解，当我打开某些文件并且未执行语法突出显示时会抛出以下错误消息。但是，如果我通过删除一行左右的代码来编辑文件，语法高亮显示将再次出现。
浏览并搜索堆栈跟踪并没有给我任何可能出错的真正指示，所以我在这里。你知道什么可能是错的吗？
我已经尝试清除缓存、重新安装并在 Android Studio 中使用不同的设置进行播放，但没有任何效果，这让我相信这与项目直接相关。此外，如果我创建一个新项目，语法突出显示会正常工作。

最佳答案
自然而然地，在发布问题时，解决方案会在不久后自行显示。
我在一个类(实体)中覆盖了 equals 和哈希码，并且两种方法都标记为 final方法。每当数据类扩展实体时，问题就会出现，我猜是因为它试图创建自己的 equals 和 hashcode 方法，但不能。
希望这对其他人有帮助!我认为该行为是正确的(数据类具有非常具体的等号/哈希码)，因此我不认为这是 Kotlin 插件中的错误，但将来最好提供更好的错误消息。
