AAPT错误：资源可提取/…找不到

Question

在最近升级了我的android工作室后，我不能再构建我的项目了。

error: resource drawable/splash_screen (aka com.whereisthemonkey.nowalism:drawable/splash_screen) not found.
Message{kind=ERROR, text=error: resource drawable/splash_screen (aka com.whereisthemonkey.nowalism:drawable/splash_screen) not found., sources=[C:\Users\Lucas\.gradle\caches\transforms-1\files-1.1\appcompat-v7-27.1.1.aar\cf575568f869a44c685b16e47de83a28\res\values\values.xml:1632:5-84], original message=, tool name=Optional.of(AAPT)}

重建、清理项目和使缓存无效都不起作用！

添加android.enableaapt2=false行并不能解决真正的问题，因此我宁愿找到问题的根源。

下面显示了我的gradle.build文件：

在我的例子中，它是一个xml选择器。在第一行中，我有两个（多亏了在我的文件中复制粘贴）：

<?xml version="1.0" encoding="utf-8"?>

而Android Studio也没有给出任何警告什么的。删除它解决了这个问题，但它需要一个完全干净的构建之后。
