Unreal Engine 插件中的 4.20 构建错误：[Adaptive unity build] 为排除的文件禁用 PCH

Question

更新到 Unreal 4.20 后尝试构建项目时，我运行在插件代码中遇到以下错误：

1>[Adaptive unity build] Disabling PCH for excluded files. Set bAdaptiveUnityDisablesPCH to false in BuildConfiguration.xml to change this behavior. 
1>[Adaptive unity build] Excluded from MyUnrealPlugin unity file: MyFile.cpp

作为实验，我按照错误消息的建议禁用了 bAdaptiveUnityDisablesPCH，但这样做只是将上面的错误替换为：

<>c.<PrintExceptionInfo>b__4_1: ==============================================================================
<>c.<PrintExceptionInfo>b__4_0: UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: E:\GameDirectory\UE4\MyGame\Plugins\MyPlugin\Intermediate\Build\Win64\UE4Editor\Development\MyPlugin\UE4Editor-MyPlugin.lib

<>c.<PrintExceptionInfo>b__4_1: ==============================================================================

关于我应该如何纠正这个问题有什么想法吗？

非常感谢！

结果是转移注意力 - 实际错误在构建输出中更靠前，源于 Windows 10 SDK 中的一个错误，该错误之前在 Win8 SDK 中被视为警告.在这种情况下，这些错误对我们没有意义，因此禁用它们可以解决问题。

#pragma warning(disable:4668)   // x  is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
#pragma warning(disable:4005)   // 'TEXT': macro redefinition

自己搜索发现“[Adaptive unity build] Excluded from XXX unity file:”后面列出的文件是根据git修改的cpp文件。

不太确定这是否能解决您的问题，但它帮助我停止追寻此消息。
